The wavelength ?max at which the spectral radiancy of a cavity radiator has its maximum value for a particular temprature T is give by the Winch displacament law, or ?maxT=a constant (=2.898X10^-3 m.K). The efective surface tempratureof the sun is 5800 K. At what wavelenght would you expect the sun radiate most strongly? In what region spectrum is this?
