To measure temperatures, physicists often use the variation of intensity of EM radiation emitted by an object. The wavelength at which the intensity is greatest is given by the equation: λ max T = 0.2898 cm.K where λ max is the wavelength of greatest intensity and T is the temperature of the object in kelvins. In 1965, microwave radiation peaking at λ max = 0.107 cm was discovered coming in all directions from space. To what temperature, in a) K b) °C c) °F, does this wavelength correspond?
