Rainbow secret

When I was a child, I was greedy. When I saw something new, I always grabbed it and played it.

I remember one Sunday when I was five years old, my father and mother went to the hospital to visit their loved ones. I stayed at the house, sat down and sat down, and started to sleep and sleep. "It’s boring!" I thought, "Go to the bathroom and have fun!" I stood on the bench, picked up the flashlight, lifted it up high, and shone it on the mirror. "Hey," the bathroom was bright, so glaring, I thought: "Blind with translucent gauze, it won't It would be so glaring." So, I was covered with gauze, and I could see everything outside, and turned on the flashlight. Suddenly, there was a "rainbow" in the mirror. I screamed "Wow": "Ghost. At this time, the gauze fell off the head, and the "ghost" disappeared. I was very curious, and covered the gauze. "Rainbow" appeared again. "It is not a ghost!" I said to myself: "This is what happened?"

One year, two years, three years, after five years, this mystery was uncovered.

On August 8, 2019, when I opened our love of science 6, I saw the secret of "Fo Guang" and I realized that this phenomenon is caused by the diffraction of light. When light passes through the edge or pore of a small obstacle during the propagation process, the direction of propagation will bend. This phenomenon is the diffraction phenomenon of light. The degree of light bending at different wavelengths is different. In the experiment, the light encounters the diffraction phenomenon of the gauze. Since the wavelengths of light of different colors are different and the degree of bending is different, various colors are separated from the white light to form a seven-color aura.

Science is ubiquitous, the mystery of small science, we must be a caring person, do more science experiments.
