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).
Take away concepts. 1  The sun emits mostly visible light. 2  Visible light, or the colors that we see are parts of the electromagnetic radiation spectrum.  The Earth emits mostly longer wavelength infrared radiation that we cannot see.
