Wien's displacement law

Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the relationship between peak wavelength and temperature.

The spectrum of a star is used to measure its radial velocity with respect to the Sun, the component of the star's velocity vector that is pa rallel to a vector connecting the star's centre to the centre of the Sun. The measurement relies on the Doppler effect, in which rad iation is shiftedin frequency when the source is moving towards or away from the observer. When a star emitting electromagnetic radiation of frequency v moves with a speed s relative to an observer, the observer detects radiation of f requency vreceding, = vf or vapproaching = v/f, where f = {(1 - s/c)/(1 + s/c)}1/2 and c is the speed of light.
