2. The number of clouds reaches its peak, and a day is half of Ming Jiang. -Bo Yang Wanli (Song)
The first sentence asks, "Why is the sunlight blocked by the mountain peak?" The second sentence asks, "Why do you have to push away the clouds on the mountainside to see the summit, and the sun can only shine into the river through the cracks in the clouds?" In fact, they all use the principle of straight-line propagation of light.
3. Baochai shines brightly and can be distinguished in the mirror. -"For Women" Qin Jia (Korea)
The first sentence shows that the reflected light after being reflected by jewelry enters people's eyes, which is particularly dazzling; The latter sentence uses the knowledge of plane mirror imaging.
4. Hold Shuiyue in your hand and let the fragrance of flowers permeate your clothes. ── "Spring Mountain jathyapple" in Liang Shi.
The previous sentence asked, "Why is there a moon in the water?" This phenomenon involves the physical knowledge of plane mirror imaging; The last sentence shows that the molecules that secrete fragrance in flowers move irregularly and have spread.
5. Until, holding up my cup, I asked the bright moon to bring me my shadow and let the three of us. ── "Drinking the Bright Moon Alone" Li Bai (Tang)
The last sentence mainly explains the phenomenon of the moon imaging in the wine glass, which involves the reflection of light. According to the meaning of the poem, the last sentence can be understood from a physical point of view as: people, the shadow under the moon, the people in the glass become three people.
6. The setting sun shines in the peach blossom room, and the willows are all red. -"Rain Window Dispels Meaning" Niu Yingzhi (Qing)
Catkin was originally white, but the main reason why the poem said it was "patches of red" was that sunlight contained seven colors of light. When it passes through a piece of red peach blossom, most of the white light is absorbed by the peach blossom, only the red light is reflected, and the reflected red light shines on the white catkin, naturally showing a faint red color.
7. How vast the world is, how close the trees are to heaven and how close the moon is to the water! . -Sleeping at Jiande Meng Haoran (Tang)
The optical principle of "approaching the moon" is illustrated by drawing the reflected light path of the image of the moon in water and the refracted light path diagram of the moon seen by human eyes in water. As shown in the figure, S 1 is the virtual image of the moon S in the water, and the light of S 1 emitted into the air is refracted on the water surface, and the refracted light deviates from the normal. When the eyes look against the refracted light, they think it is S2 in the water.
2. Poetry related to optics 1. Li Bai's poem "Until, raise my cup, I ask the bright moon and drink three people" is a straight line of light propagation.
2. Liu Yuxi's poem "The lake and the moon know each other, and there is no wind mirror on the pool."
3. The linear propagation of light in Lu's poems "If you want to climb high and look far, you will never leave your ileum".
4. The linear propagation of light in Su Shi's poem "How clever the peak is to block the sun, and the river is far away from the sky".
5. The light reflection of Qin Jiashi's poem "Baochai shines brightly, and the mirror can identify the shape".
6. Wang Weishi's voice "There seems to be no one on the empty mountain, but I think I heard a voice" is generated by the vibration of the object.
7. The linear propagation of light in Gao Shi's poem "Climbing to see a hundred miles, Sangtianwang".
8. The linear propagation of light in Dai Fugu's poems "blocks the sky and the sun, and the stone screen is high".
9. Li Chang's summer poem "The bright moon leaves the cloud cliff and flies out of the thin front porch".
10. The sound of "Hanshan Temple outside Gusu City, Midnight Bells to Passenger Ships" in Zhang Jishi is produced by the vibration of objects.
