The Wien displacement law states that the wavelength of maximum emission, A , of a blackbody varies inversely with absolute temperature the product A T remains constant. When A is expressed in micrometers, the law becomes... [Pg.727]

Light emitted from a black body solely as a result of high temperature as in electric bulb is known as incandescence or thermal radiation. The quality and quantity of thermal radiation is a function of temperature only. The wavelength of most strongly emitted radiation in the continuous spectrum from black body is given by Wien s Displacement Law-, Amax T —h. (where h is Wien s constant = 2.898 X 10 3 m deg). [Pg.10]

Wien displacement law Approximate formula for the wavelength, X, of maximum blackbody emission Xmax - T hc/5k — 2.878 X 10" 3 m K, where T is temperature in kelvins, h is Planck s constant, c is the speed of light, and k is Boltzmann s constant. Valid for T > 100 K. working electrode One at which the reaction of interest occurs. [Pg.705]

By properly choosing the value of the constant ft, Planck found that Eq. (19.11) agreed with the measured distribution within the experimental error To find the maximum, we set duJdX = 0 the Wien displacement law is obtained in the form... [Pg.455]

The Wien displacement law for blackbody radiators states that the product of temperature in kelvin and the wavelength of maximum emission is a constant k k - T - Calculate the wavelength of maximum emission for a Globar infrared source operated at 18(X) K. Use the data In Figure 6-22 for the Nernst glower for the evaluation of the constant. [Pg.160]
