Frequency of infrared rays
WebWaves in the THF frequency band are known as terahertz waves, T-waves or T-rays. The upper limit is usually 3,000 GHz or 3 THz (1 THz = 1,000 GHz) although some sources designate it as 30 THz. Terahertz radiation begins at a wavelength of around a millimeter and proceeds into shorter wavelengths. WebRadio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in ...
