1. Principle
,
After being irradiated by sunlight and ultraviolet rays, it absorbs sunlight and ultraviolet energy, resulting in changes in the molecular structure, resulting in changes in the absorption wavelength, and color changes. When sunlight and ultraviolet energy are lost, they will be restored. The original molecular structure is restored to the original color.
B.
Basic knowledge of spectrum: Ultraviolet rays are divided into three types according to different wavelength bands. Those with wavelengths within the following are B, those with wavelengths within 3. The visible light range is 3-, and the infrared light range is -
,
