Spectral Distribution of black body #blackbody

#physics #12th #kinetictheory aik this video we have explained in detail about spectral distribution of black body of kinetic theory of Gases and radiation Fig. 3.5: Radiant power of a blackbody per unit range of wavelength as a function of wavelength. that From experimental curves, it is observed 12 at a given temperature, the energy is not uniformly distributed in the spectrum (i.e., as a function of wavelength) of blackbody, 2. at a given temperature, the radiant power emitted initially increases with increase of wavelength, reaches it's maximum and then decreases. The wavelength corresponding to the radiation of maximum intensity, Amax, is characteristic of the temperature of the radiating body. (Remember, it is not the maximum wavelength emitted by the object), 3. area under the curve represents total energy emitted per unit time per unit area by the blackbody at all wavelengths, 69 4. the peak of the curves shifts towards the left shorter wavelengths, i.e., the value of max decreases with increase in temperature, 5. at higher temperatures, the radiant power stor total energy emitted per unit time per
