Displacement law, Wien

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]

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]

Putting this in the same form as the Wien displacement law, we get ... [Pg.155]

Weight - That force which, when applied to a body, would give it an acceleration equal to the local acceleration of gravity. [1] Wiedeman-Franz law - The law stating that the thermal conductivity k and electrical conductivity a of a pure metal are related hyk = LaT, where T is the temperature and L (called the Forenz ratio) has the approximate value 2.45 x 10" W/IG. Wien displacement law - The relation, which can be derived from the Planck formula for black body radiation, that... [Pg.118]

Planck took the extraordinary step of setting e inversely proportional to the wavelength, recognizing that the Wien displacement law would come out of the resulting equation. Since the frequency times the wavelength is equal to the velocity, we have l/X = v/c, where v is the frequency and c the velocity. Setting e proportional to l/X is equivalent to setting it proportional to the frequency ... [Pg.455]

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]
