Light is the radiant energy that travels in the form of electromagnetic waves. Electromagnetic wave radiation has a wide range of wavelengths, only wavelengths in the 380 to 760nm of this part of the radiation to cause light vision, known as visible light. Wavelengths shorter than 380nm light is ultraviolet, x-rays, γ-rays; longer than 760nm light is infrared, radio waves, etc., they do not produce light vision to the human eye, that is, invisible. Therefore, light is an objective existence of e
