Physical principles: reflection and refraction of light.
The mountains are stacked in the water, and there is a reflection of the mountains in the water. There is no unattractive mountain, no unattractive water.
Second, Hanshan Temple outside Gusu City, the midnight bell goes to the passenger ship. -Zhang Tang Ji "Sleeping in Fengjiang"
The spread of sound.
In the lonely and quiet Hanshan Temple outside Gusu, the bell rang to the passenger ship in the middle of the night.
Third, the green hills on both sides of the strait are opposite, and the sails are coming alone. -Tang Li Bai's "Looking at Tianmen Mountain"
Physical principle: Castle Peak is static relative to the ground, but with the moving ship as the reference, Castle Peak becomes moving, with the river bank as the reference, and the solitary sail comes from the sun.
The beautiful scenery of the green hills on both sides of the strait is inseparable, and a solitary boat comes from the horizon.
April, April, beautiful scenery on earth, peach blossoms in mountain temples. -Tang Bai Juyi's Peach Blossom in Dalin Temple
Physical principle: The higher the terrain, the slower the temperature rises. In the same season, the temperature on the mountain is lower than that on the mountain.
In April, all the flowers have withered, and the peach blossoms in the ancient temple in the mountains have just bloomed.
Verb (abbreviation of verb) How the water of the Yellow River flows out of heaven and into the ocean, which is gone forever. -Tang Li Bai's "Into the Wine"
Physical principle: water cycle.
The water of the Yellow River fell from the sky, and the waves rolled straight into the East China Sea, never to return.
2. An ancient poem containing physical knowledge'' The apes on both sides of the strait can't stop crying, and the solitary sails come from the sun'': 1. According to the principle of lever balance, if the power arm is a fraction of the resistance arm, then the power is several times the resistance.
If the weight of the arm is very large, it is entirely possible to "dial one or two kilograms." 2. A broken mirror cannot be reunited: when the distance between molecules is large (more than several hundred angstroms), the attraction between molecules is very small, almost zero, so it is difficult to reunite a broken mirror.
What you can't catch is the flower in the water that you can't catch in the mirror: the flat mirror forms a virtual image. 4, people are United, Taishan moves: if the component directions are the same, the resultant force is equal to the sum of the components.
5, hemp rope to lift tofu-can't lift it: when the pressure is constant, if the stress area is small, the pressure will be great. 6. "True gold is not afraid of fire, and truth is not afraid of argument.
"From the point of view of the melting point of gold, although it is not the highest, it also has 1068℃, while the general flame temperature is around 800℃. Because the temperature of the flame is lower than the melting point of gold, gold cannot be melted. 7. The moon is dizzy and windy, and the foundation is wet and rainy: when the wind comes, the temperature in the upper air drops rapidly and the water vapor condenses into small drops. These small water droplets are equivalent to many prisms, and the moonlight is scattered through these "prisms" to form a colorful halo, so it is said that "the halo is windy."
The basic nourishment is the ground against the tide. Before the rainstorm, the air humidity is high, the ground temperature is low, and the water vapor near the ground condenses into small water droplets. In addition, the salt contained in the ground is easy to absorb wet water vapor, so the ground is against the tide, which indicates shanghai dawn. 8, a long whistle, the sound of the mountain is like a valley: people whistle in the mountains, and the sound can form a loud echo after repeated reflection, which lasts for a long time. As if the mountains were shouting and the valleys were echoing.
9. But you can't see people when you listen to the sound: when the size of the obstacle is smaller than the wavelength, obvious diffraction will occur during the wave propagation. Generally, the height of the fence is several meters, and the wavelength of sound wave is larger than the height of the fence, so you can enclose the high wall for people outside the wall to hear; The wavelength of light wave is shorter (about 10-6 meters), which is much smaller than the size of a high wall, so the light emitted by people cannot be diffracted outside the wall, and people outside the wall can't see people inside the wall.
10, boiling water doesn't ring, water doesn't ring: Before the water boils, bubbles in the water rise and vibrate up and down due to convection, and most bubbles burst under the pressure of water, and their cracking and vibrating sounds ring with the container, so the sound is very loud. After water boils, it is isothermal up and down, and the bubble volume increases. Under the action of buoyancy, it will explode when it reaches the water surface, so the noise is relatively small.
1 1, Pig Bajie looks in the mirror-inside and outside are not people: according to the imaging law of plane mirror, the images formed by plane mirror are equal in size and the objects are symmetrical, so what Pig Bajie sees is "exactly the same" as himself, or the image of a pig, and naturally "inside and outside are not people". 12, fire and water incompatibility: when a substance burns, it must reach the ignition point. Because of the large specific heat of water, water can absorb a lot of heat when it comes into contact with fire, which reduces the temperature of the ignited object; At the same time, the vaporized water vapor surrounds the burning object, making it impossible for the object to contact with air. Without air, combustion cannot be carried out.
13, a day in a cave, the world has passed thousands of years: according to Einstein's theory of relativity, sailing in a spaceship near the speed of light, the passage of time will be much slower than on earth. Living in this "cave" for a few days, the earth has spent several years, decades, even hundreds and thousands of years. 14, Clairvoyance, Clairvoyance: People use electromagnetic waves to transmit sound and image signals, making the ancient myth of "Clairvoyance, Clairvoyance" come true.
And human vision has far exceeded "thousands of miles". 15, sitting on the ground and walking 80,000 miles a day: Because the radius of the earth is 6,370 kilometers, the distance that objects on its surface "walk" is about 40,003.6 kilometers, which is about 80,000 miles.
This is a poem sung by Mao Zedong. It also scientifically reveals the relationship between motion and stillness-motion is absolute and stillness is always relative to the reference object. 16, pot bottom: there are two conditions for liquid boiling: one is to reach the boiling point, and the other is to continue to absorb heat.
If you take a salary, you can stop the liquid from boiling. 17, flowers in the wall are fragrant outside the wall: flowers in the wall will spread outside the wall because of irregular movement.
18. Looking at the sky from the well, you can see very little: because light travels along a straight line, according to the knowledge of geometric drawing, the frog's field of vision will be very small. 19, fidgeting: According to the pressure formula, when the pressure is constant, the smaller the stress area, the greater the pressure.
People will feel very uncomfortable sitting on such a blanket. 20. Xue Ruifeng shines brilliantly in the new year: Because snow is a poor conductor of heat, when it covers crops, it can well prevent heat conduction and air convection, so it can play a role in heat preservation.
2 1, "It is cold before frost and cold after snow." In late autumn night, the air temperature near the ground suddenly becomes cold (the temperature is below 0℃), and the water vapor in the air condenses into small ice crystals and adheres to the ground to form frost, so it feels "cold before frost".
When snow melts, it needs to absorb heat to reduce the temperature of the air, so we have the feeling of "cold after snow". 22. "A drop of water can see the sun, but everything can see the spirit.
"A drop of water is equivalent to a convex lens. According to the law of convex lens imaging, you can see the image of the sun through a drop of water. 23, the egg hits the stone-step by step, the egg hits the stone, although the force is the same, but the pressure that each object can bear is certain, beyond this limit, the object may be damaged.
Eggs can withstand less pressure, so they will break. 24, paper can't wrap paper, and it will burn when it reaches the ignition point.
25. It has the natural fragrance of musk deer, so you don't have to breathe in the wind. 26. Before the jade is polished, the surface is uneven and the light is diffuse. After the jade is polished, the surface is smooth and the light is mirrored.
27. "The fan has a cool breeze, which is suitable for summer and not for winter." When the fan is used in summer, the air flow is accelerated, which makes the sweat on the human surface evaporate quickly. Because evaporation absorbs heat, people feel cool.
28. "Man struggles upwards, but water flows downwards." It is an objective law of nature that water flows downwards, because water flows downwards from a height under the action of gravity.
Flowers in the wall, fragrance outside the wall (diffusion phenomenon), the moon in the water that can't be caught, the flowers in the mirror that can't be picked (the flat mirror is a virtual image), the pool water reflects the bright moon, and the pool water is clear.
3. Poems, proverbs or idioms related to physical knowledge are all 1, which is called "one thousand kilograms"-according to the principle of lever balance, if the power arm is a fraction of the resistance arm, then the power is several times the resistance. If the load-bearing arm is large, it is entirely possible to "dial one or two kilograms."
2. Broken mirrors cannot be reassembled-when the distance between molecules is large (more than several hundred angstroms), the attraction between molecules is very small, almost zero, so it is difficult to reassemble broken mirrors.
What you can't catch is the flowers in the water that the mirror can't catch-the flat mirror forms a virtual image.
4. Everyone is United, and Mount Tai is the top-if the components are in the same direction, the resultant force is equal to the sum of the components.
5, hemp rope to lift tofu-can't lift it-when the pressure is constant, if the stress area is small, the pressure will be great. True gold is not afraid of fire, and truth is not afraid of argument-although the melting point of gold is not the highest, it is 1068℃, while the temperature of general flame is about 800℃. Because the temperature of the flame is lower than the melting point of gold, gold cannot be melted.
7, the moon is dizzy and the wind is blowing, and the foundation is wet and rainy-when the wind comes, the air temperature drops rapidly and the water vapor condenses into small drops. These small water droplets are equivalent to many prisms, and the moonlight is dispersed through these "prisms" to form colorful halos, so it is called "moon halo wind".
The basic nourishment is the ground against the tide. Before the rainstorm, the air humidity is high, the ground temperature is low, and the water vapor near the ground condenses into small water droplets. In addition, the salt contained in the ground is easy to absorb wet water vapor, so the ground is against the tide, which indicates shanghai dawn.
8, a long whistle, the sound of mountains and valleys should be-people shouting in the mountains, the sound can form a loud echo after repeated reflection, lasting for a long time. As if the mountains were shouting and the valleys were echoing.

5. Find a poem containing physical knowledge and point out what physical knowledge it contains. 1, Hanshan Temple outside Gusu City, the bell rang to the passenger ship at midnight.
2, "Bai Di's words in the clouds, a thousand miles in Jiangling one day. The apes on both sides of the strait can't stop crying, and the canoe has passed Chung Shan Man. " (The Early Development of Baidicheng by Li Bai in Tang Dynasty)
Analysis: The first two poems literally mean that the poet has to go back and forth to Jiangling in one day, that is, it takes 12 hours (1000 km = 1000 km) to travel 2000 miles. According to this, roughly calculate the ship speed: v=s/t= 1000 km/12 hours ≈ 83.33 km/h. The speed of modern inland steamboat is only 10 ~ 2 1.6km/h, which is too fast for Li Bai. In fact, this is an expression of the poet's eagerness to return.
3. "When my boat was sailing in the fog, the day was getting dark and old memories began. How vast the world is, how close the trees are to heaven, and how close the moon is to the water! . "(Meng Haoran's Sleeping at Jiande in the Tang Dynasty)
Analysis: The poet is still enjoying the night scene in the hotel with great interest. The water in Jiande River is so clear and calm. The poet takes water as a mirror, and the bright moon seems close at hand, so he can sit back and relax tonight. It is clearly a "flat mirror" that makes the bright moon in the sky "image" in the water.
4. Wen Tianxiang, a national hero of the Southern Song Dynasty, once vowed by the Yangtze River that "my heart is a magnet, not the south." . Here, the author uses the magnetic needle stone to compare his determination to resist gold.
Analysis: One of the properties of magnets refers to the north and south, so Wen Tianxiang used the property of "the needle stone refers to the north and south" to compare his determination to resist gold. This makes people involuntarily think of Wen Tianxiang's famous sentence "Who has never died since ancient times, keep the heart of Dan and follow the history". Today's people are encouraged, and their feelings with the ancients are deafening, which inspires their deep patriotic feelings.
5, the fragrance of flowers is warm at first sight, the sound of singing through the trees is happy, and the sun is shining. "These are two poems written by Lu You, a poet in the Southern Song Dynasty, in Happy Village. From the physical point of view, the first sentence can be understood as: the aromatic oil molecules secreted by flowers accelerated, indicating that the surrounding temperature was sudden at that time.
Analysis: The poet expressed his admiration for the beautiful nature with a beautiful style and accurately described the details in the process of seasonal alternation. "The fragrance of flowers attacks people" shows that the poet has already felt the fragrance of flowers without touching them, which is caused by the irregular movement (diffusion) of aromatic oil molecules secreted by flowers; When the temperature around you suddenly rises, you will feel "sudden warmth".
6. The small bamboo raft is in the middle reaches of the river, walking on both sides of the towering green hills. "These two lyrics have long been deeply rooted in the hearts of the people with the famous movie" Sparkling Red Star ". Please use your knowledge of physics to analyze these phenomena.
Analysis: "Walking" and "swimming" represent two different movements, which are called mechanical movements in physics. Whether the "swimming" of bamboo rafts in the river depends on the ground or the green hills on the ground; "Walking" on both sides of "Castle Peak" is actually an anthropomorphic statement. People are standing on the "bamboo raft". If the bamboo raft is used as a reference, then the green hills are moving!
7. Hold Shuiyue in your hand and let the fragrance of flowers permeate your clothes.
Physical knowledge:
"Holding the moon in the hand" is a mirror reflection phenomenon.
"Clothes are full of flowers" is a phenomenon of molecular diffusion.
8. Rizhao incense burner produces purple smoke. Looking at the waterfall hanging in Qianchuan from a distance, I went straight down to thousands of feet. Suspected that the Milky Way had fallen for nine days.
Physical knowledge: the kinetic energy of "flying water" is increasing, while the gravitational potential energy of water is decreasing.
9, the peaks reflect the mountains, no mountains, no water, no ecstasy.
Physical knowledge: reflection and refraction of light
10, peach blossoms set each other off in red
Physical knowledge: The red light reflected by peach blossoms is the decisive factor for the color of objects.
1 1, you can tell a person by his voice.
Physical knowledge: timbre, one of the three characteristics of music.
12, a poem by Li Yi, a poet in the Tang Dynasty, is called "Happy to see my brother goodbye", which describes: "After these ten years of boredom, we meet again. We have all changed a lot. The first time I heard your last name, I thought you were a stranger. Then I heard your name, and I remembered your young face. As can be seen from "Ask the surname", there is a feature in the voice that reminds the poet of his memory ten years ago. This feature is one of the three major features of music.
I wonder if it's enough?
6. Ancient poems, proverbs and sayings about physics 12: refraction and reflection of light among colorful clouds in Bai Di.
Jiangling, thousands of miles away, the relationship between distance and time.
Apes on both sides of the strait can't stop crying, and their voices are generated and spread.
The canoe has passed through Chung Shan Man, and the change of object position is called mechanical movement.
First, the energy knowledge in ancient poetry
1. Su Shi's poem "Bow like a full moon, look northwest, shoot Sirius". The energy conversion involved in poetry is the conversion from elastic potential energy to kinetic energy.
2. Li Bai's poem "Flying down three thousands of feet, it is suspected that the Milky Way has set for nine days". Waterfalls in poetry contain great mechanical energy.
Second, the reference knowledge in ancient poetry.
1, Mao Zedong's poem "Sit on the ground and walk 80,000 miles a day, overlook the sky and see John Wan" means that "sit on the ground" is static relative to the ground, and "walk on the sky" is moving relative to the sun.
2. Li Bai wrote in the poem "Looking at Tianmen Mountain" that "the green hills on both sides of the strait look at each other and sail alone." "Castle Peak Opposite" is set in a boat, and "Lonely Sail from the Sun" is set in a river bank.
3. In the lyrics of "Sparkling Red Star", "The small bamboo raft is in the middle reaches of the river and walks on both sides of the towering green hills". The Middle Reach of the Bamboo Raft River takes the earth as the reference, and A Cross-strait Journey on the Green Mountain takes the ship as the reference.
4. "A strong wind blew the well outside the fence last night." The well was blown away and the fence was used as a reference.
Third, the knowledge of thermodynamics and molecular dynamics in ancient poetry
1. In Lu You's Village Living in Mountain Happiness, "the flowers smell like sudden warmth, and the sound of magpies passing through the trees is like a new sunny day". The "fragrance of flowers" in poetry is the result of irregular movement of aromatic oil molecules secreted by flowers, and temperature affects the intensity of molecular movement.
2. In Zhang Xu's Stay in the Mountain, "even if there is no rain, the clothes are stuck in the depths of the areola". -Dew formation (liquefaction).
3. Bai Juyi's "Mu Jiang Yin" "Poor September is late at night, dew is like a pearl and the moon is like a bow"-the formation of dew (liquefaction).
