Vedclass · Answer

(B) black body is an idealized physical body that absorbs all incident electromagnetic radiation. According to Planck's law of black body radiation, the intensity of radiation emitted by a black body depends on the wavelength $(\lambda)$ and the temperature $(T)$ of the body. The intensity distribution is not uniform across all wavelengths. For a given temperature, the intensity increases with wavelength up to a peak value (corresponding to the peak wavelength $\lambda_{max}$) and then decreases as the wavelength increases further. Therefore, the statement that 'Intensity is same for all wavelengths' is incorrect.

Out of the following, which statement is $NOT$ true about black body radiation?
