What are the applications of light reflection?

1. Seeing the road clearly during the day is because the road surface (diffuse reflection) reflects sunlight;

2. Look at the moon at night, because the moon reflects sunlight;

3. See the reflection in the water, because water reflects sunlight;

4, reading under the lamp, because paper can reflect light;

5. The computer is facing the window, and the screen can't be seen clearly because the screen reflects sunlight;

6. Look in the mirror and use the principle that the mirror reflects light;

7. On the road at night, the puddle is very bright because the water surface (completely) reflects (illuminates) the moonlight;

8, movies, blackboards, using diffuse reflection of light;

9. On the back of the smooth metal spoon, there is a convex mirror, and you can see the reduced object image, which is the reflection phenomenon of light;

10, the expressway has a perfect reflective marking system, including hot-melt reflective marking, coated reflective delineator, luminous nails, etc. , which can reflect the lane indicator line, roadside profile, lane dividing line and median profile under vehicle illumination.

In short, all visible objects, except those that can refract light, emit light and store light (night light), are almost all due to reflection (and scattering, that's all, I really can't think of anything else).
