Light travels in the form of electromagnetic waves. The light source is an electromagnetic wave that can be felt by people’s eyes, and its wavelength range is 380nm-780nm (nm: nanometer, length unit 1nm=10-9 m). Those longer than 780nm are infrared, radio, etc., and those shorter than 380nm are ultraviolet, X-ray, cosmic rays, etc.
The visible light part is further divided into seven basic monochromatic lights: red light, yellow light, orange light, green light, cyan light, blue light, and purple light.… Read More
