Explain the blackbody radiation spectrum in terms of wavelength |
Answer» Solution :Blackbody radiation is the electromagnetic radiation emitted by a blackbody by virtue of its temperature. It extends over the whole range of wavelengths of electromagnetic waves. The distribution of energy over this entire range as a function of wavelength or FREQUENCY is known as the blackbody radiation SPECTRUM.  If `E_lamda` is the emissive POWER of a blackbody in the wavelength rang `lamda` and `lamada+d lamada,` the energy it emits per UNIT AREA per unit time in this wavelength range depends on its absolute temperature T. the wavelength `lamda` and the size of the interval `d lamda.` |
