At a given temperature a body emits energy of a single wavelength corresponding to that temperature. True or False?(a) True(b) FalseThe question was asked in quiz.This is a very interesting question from Thermal Properties of Matter in portion Thermal Properties of Matter of Physics – Class 11

Answer»

The correct choice is (b) False

The best explanation: THERMAL radiation from a body shows a CONTINUOUS spectrum of WAVELENGTHS. But at a given TEMPERATURE there is a particular short range of wavelengths which contributes the maximum to the total radiant energy. The graph given below shows the intensity of different wavelengths at different temperatures.
