Physicists and astronomers often use measurements of this electromagnetic radiation to determine the temperature of an object. The wavelength Amax at which the intensity of this "thermal radiation" is greatest is inversely proportional to the temperature i.e. given by an equation Amax = C/T, for some constant C. The precise relationship is plotted in the graph above. In 1965, microwave radiation peaking at Amax= 0.107cm was discovered coming in all directions from space. To which temperature does this correspond? This is the ambient temperature of the universe, i.e., the temperature that an object in outer space far from any stars will have once it comes to equilibrium. Where did this radiation come from (Google "cosmic microwave background")?
