Infrared (IR) is invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz) to 1 mm (300 GHz) (although people can see infrared up to at least 1050 nm in experiments).
(a) Visible light is a form of electromagnetic radiation. (b) The frequency of radiation increases as the wavelength increases. (c) Ultraviolet light has longer wavelengths than visible light. (d) Electromagnetic radiation and sound waves travel at the same speed.
