"Writing from a Guest"
Li Bai
Lanling wine and tulips, jade bowls filled with amber light.
But the host can make the guests drunk, and they don’t know where they are in a foreign country.
Butterflies Dance in the Spring Garden
Spring flowers are not worth a few degrees of frost, who is alone with the autumn moon;
If the infatuated heart meets true love, the dancing butterflies Wear red makeup. The poem with "light" is as follows: The bright moon shines brightly at night, prompting the weaving of the east wall. The light of the mountain is pleasing to the birds, and the shadow of the pond is empty of the human heart. Thousands of miles of mountains and rivers were no longer a dream yesterday, but the autumn scenery is like this in the blink of an eye. Nian Nujiao to the Moon during the Mid-Autumn Festival Ming, Wen Zhengming, Xing Xiangzi "The sky and the autumn light, the love turns to be sad, and the exploration of gold and Yingzhi is approaching the Double Ninth Festival." The time is rushing, the fragrant orchids are resting, and the good flowers fade, but only in an instant. The fragrance of autumn pistils leads to the Mid-Autumn Festival. Climb the tower and look at the moon (Mi Fu, Song Dynasty). The Huaihai Sea is full of silver, and thousands of rainbow lights nurture the treasures of clams. Song Su Shi's "Seeing the Moon in the Mid-Autumn Festival and Ziyou" The bright moon is not high in the mountains, and the auspicious light is thousands of feet long. There is a pregnant woman under the moon in the autumn night (Meng Haoran) The bright moon hangs in the autumn sky, moistened by the dew. When the candle is extinguished, it is filled with pity and light, and when I put on my clothes, I feel the dew. Looking at the Moon and Huaiyuan (Zhang Jiuling)
2. Poems, sayings, or idioms and physical meanings about sound phenomena and light phenomena
Deafening: refers to the loudness of the sound.
·Sing loudly: refers to the loudness of the voice.
·Whispering: refers to the low loudness of the voice.
·Pleasant: Refers to the good pitch of the voice.
·Bearing one's ears and stealing the bell: Attenuating the sound during the transmission process.
·The lingering sound: The reason is that although the knocking on the object has stopped, the object is still vibrating and producing sound.
·Overtone: There are indeed sounds beyond the human hearing frequency range, such as ultrasound and infrasound, which we cannot hear at all.
·Partition walls have ears: This shows that solid objects can transmit sound.
·A long roar, the mountains and valleys echo. When a person shouts in the high mountains, the sound can form an echo through multiple reflections, lasting for a long time, as if the mountains are roaring and the valleys are echoing.
·The lingering sound lingered for three days. When sound encounters objects, it reflects back to form an echo.
·Know a person by hearing his voice. Different sound emitters have different timbres of sounds, and familiar people can be distinguished based on the timbre of the sounds.
·But I heard his voice but could not see him. Sound waves encounter obstacles during propagation. When the wavelength is larger than the size of the obstacle, the sound waves can bypass the obstacles, and solids can also transmit sound, so sound can be heard; while light propagates in a straight line in the air. The line of sight is easily blocked by obstacles, so people cannot be seen.
·The boiling water does not make a sound, the sound of the water does not boil. When water is boiled, the water at the bottom of the pot absorbs heat and vaporizes to form bubbles. When the water is not boiling, these bubbles rise from the bottom and encounter the lower temperature water in the upper layer. The water vapor inside the bubbles will liquefy into water, and the volume of the bubbles will gradually shrink until they disappear. The expansion and contraction of the bubbles causes the water to vibrate, causing a sound. When the water is boiling, the temperature of the water at the bottom of the pot is equal to that of the water in the upper layer. As the bubbles rise, water vapor is continuously generated, and the volume becomes larger. When it reaches the water surface, it bursts and the vibration is small. Therefore, "the sound of water does not boil, and the sound of boiling water does not sound." .
·In Hanshan Temple outside Gusu City, the midnight bell rang for the passenger ship. We can learn from this that the sound of bells is transmitted to the passenger ship through the air, and the sound of the bells is identified based on the timbre of the sound.
·Don’t dare to speak loudly for fear of frightening the heavens. The "high" here refers to the high pitch of the sound. But people in the Heavenly Palace will not hear your voice, because sound cannot be transmitted in a vacuum.
·After ten years of separation, we met again when we were grown up. We were surprised when we first met each other when we asked for our last names, and recalled our old appearance by calling them names. From the "asking for a surname", we think of the "old appearance" we saw at first. It can be seen that there is a feature in the voice that reminds the poet of memories from ten years ago. This feature is the timbre.
·The sound of wind, rain, and reading are all in my ears. Shows that sound can travel in air and water.
