Poetry about the phenomenon of light

1. China's ancient description of the light phenomenon, such as: "You can't catch the moon in the water, but you can't pick the reflection. Refraction analysis: plane mirror imaging belongs to the reflection phenomenon of light; According to the imaging of plane mirror, the phenomena of "moon in water" and "flower in mirror" are analyzed. The refraction of light is a phenomenon that the propagation direction of light changes when the light is obliquely incident from one transparent medium to another. According to the analysis of plane mirror imaging and light refraction, the calm water surface is equivalent to a plane mirror, so "Moon in Water" is the image of the moon in water, while "Flower in Mirror" is the image formed by flowers in the plane mirror, which belongs to plane mirror imaging, that is, the reflection phenomenon of light. " "Shallow water" is a phenomenon that the propagation direction of light changes after it is injected into the air from water, so it belongs to the refraction phenomenon of light. Therefore, the answers are reflection and refraction.
