How to do the shiny white paper experiment?
1 white paper, 1 black paper, 1 flashlight, 1 mirror, 1 darkroom.
experimental procedure
1. In the dark room, turn on the flashlight and stand in front of the mirror.
2. Hold the flashlight to one side of your face and let it shine on your nose.
3. Hold the black paper on the other side of your face with your other hand, and then hold the white paper. Always look in the mirror during this process.
What happened?
If only a flashlight is used, it can only illuminate the nose. With black paper, your facial reflection is almost completely blurred. If you use white paper, almost the whole face will be illuminated.
Cause solution
When you only use a flashlight, the light will only reflect from the object it touches-your nose. With the help of paper, the effect of reflection depends on the color of paper. Black paper hardly reflects the light that shines on itself, while white paper reflects a lot of light. Therefore, the light shining on the white paper is reflected back to the face, almost illuminating the whole face.
