The color of mineral is the most obvious and intuitive property of mineral. It is very important to observe the color for identifying and distinguishing different minerals. And color is a kind of physiological feeling of people. When the electromagnetic radiation in the wavelength range of the visible region (390-770nm) stimulates people's visual nerve, people will have a sense of color. The selective absorption of visible light by minerals is the main reason for the color of minerals.

2. Ultraviolet:
Ultraviolet light is located outside the violet light in the spectrum, which is invisible light. It makes many substances fluoresce and makes photographic plates sensitive easily. When the ultraviolet ray irradiates the human body, it can promote the synthesis of vitamin D in the human body, so as to prevent rickets. This is the reason why children are often exposed to the sun. Ultraviolet also has the function of sterilization and disinfection. The ward in the hospital is sterilized by ultraviolet. But too strong ultraviolet can hurt human body, so we should pay attention to protection. Glass, oxygen in the atmosphere and ozone layer in the sky have strong absorption effect on ultraviolet rays. They can absorb most of the ultraviolet rays in the sunlight, so they can protect the creatures on the earth from ultraviolet rays.

3： Infrared:
Visible light refers to the visible light wave range from 390nm (violet light) to 770nm (red light), and the light with wavelength between 760nm and 1mm is called infrared light, which is invisible to the naked eye. Infrared thermal imaging uses photoelectric technology to detect the infrared specific band signal of the object's thermal radiation, transforms the signal into images and graphs that can be resolved by human vision, and further calculates the temperature value. Infrared thermal imaging technology enables people to transcend visual barriers, so that people can see the temperature distribution of the object surface.
