The wavelengths of infrared and ultraviolet visible light are 380 nm to 760 nm. The longer wavelength region is the infrared spectrum. Most of the infrared radiation on Earth comes from the sun. The region with shorter wavelengths near visible light is the ultraviolet spectrum.
Each wavelength transmits a certain amount of energy. The faster the frequencies and the shorter the wavelengths of these waves, the more energy can be transmitted. Therefore, the shorter the wavelength and the higher the frequency, the more energy is transferred into it. This means that short-wavelength radiation can penetrate the material more deeply.
