Wavelength of light and color
To light, ultraviolet radiation, infrared radiation, there is a visible light, you can not only see visible light only to humans. The figure below is what the length of the wavelength of each light was in the table.
While light is the wavelength of the waves of light they spoke of what the whether you are related, it can be said that the wavelength and color are involved. In addition, ultraviolet radiation what wavelength is shorter than the visible light humans can see, is called long ones and infrared radiation. (In addition to this there is also a thing called X-ray and microwave.) Certainly, it can not be seen in the eyes the light of light and the sun of the TV remote control. In addition, the color of the visible light from a short wavelength, has become a purple → blue → green → yellow → red. In other words, the light of the sun we can say that the length of all wavelengths are mixed is different color.
