Wein’s displacement law

The wavelength at which maximum emission takes place is related to the absolute temperature by Wein s Displacement Law, which states that the wavelength for maximum emission varies inversely with the absolute temperature of the source, or ... [Pg.440]

Figure 8.3 Spectral radiant power (per unit time per unit area) distribution of a blackbody at various temperatures. Note that the maximum intensity, even at 3500 K, is still in the infrared region of the spectrum. The displacement of the maximum of the radiant energy shifts linearly with absolute temperature (dotted lines) in accordance with Wein s displacement law.

Q.7.4 Show that (a) the Rayleigh-Jeans law is a special case of Planck distribution law for the blackbody spectrum. Show also that (b) the Wein displacement law can be derived from Planck s distribution law. [Pg.35]
