![]() The radiations are independent of the nature of the body and depend only on the temperature of the black body. Que 2: Discuss the Energy distribution curve for a Black body radiation with necessary diagram.Īns: As the radiating power of a body is proportional to its absorbing power, a black body would also radiate more strongly, at any given temperature than any other surface. The radiations emitted from the black body are independent of the nature of the body. The higher the temperature, the more light energy is emitted and the higher the frequency (shorter the wavelength) of the peak of the spectrum. So a blackbody emits a certain spectrum of light that depends only on its temperature. They emit light because they are wiggling around due to their heat content (thermal energy). The black body is a composed of atoms and molecules which can emit and absorb light.Īs the radiating power of a body is proportional to its absorbing power, a black body would also radiate more strongly at any given temperature than any other surface. ![]() The term comes from the fact that a cold blackbody appears visually black. Que 1: What is black body and black body radiation? Explain.Īns: Black body: A perfect black body is one, which absorbs radiation of all wavelength’s incident upon it.
