Light is an electromagnetic wave with a frequency of approximately since displaystyle. Hz to 4x10 ^ {14}. Displaystyle 8x10 ^ {14} Hz Or a wavelength in the range 400 to 700 nm, the human eye is more sensitive to electromagnetic radiation. Subject to high temperatures, such as incandescent light bulb with a high temperature of about 2500 degrees Celsius or sun at a temperature of about 6000 degrees Celsius to emit light. For light with a wavelength of about 700 nm eye to recognize a red light. The light with a wavelength less. Eyes are perceived as white, orange, yellow, green, blue or violet light, respectively. Which has a wavelength of about 400 nm in the light of these. When combined with the right amount. A white light
