Question

A black body radiates maximum energy around the wavelength 0. Lf the temperature of the black body is changed so that it radiates maximum energy around the wavelength 20, the ratio of power radiated now to power radiated previously is

Answer 2

All objects with a temperature above absolute zero (0 K, -273.15 oC) emit energy in the form of electromagnetic radiation. A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none.
