WebThis is known as Wien’s displacement law. Since the solar emission tempera-ture is about 6000K and the maximum of the solar spectrum is (see Fig.2.2) at about 0.6µm – i.e., in the visible – and we have determined Te=255K for the Earth, it follows that the peak of the terrestrial spectrum is at λearth m =0.6µm× 6000 255 ' 14µm. WebThe spectrum of a blackbody is continuous (it gives off some light at all wavelengths), and it has a peak at a specific wavelength. The peak of the blackbody curve in a spectrum moves to shorter wavelengths for hotter objects.
