Vedclass · Answer

(D) 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 varies with wavelength. The emission spectrum is continuous,meaning it emits radiation across all wavelengths. However,the intensity is not constant for all wavelengths; it follows a specific distribution curve (Planck's distribution) that depends on the temperature of the body. Therefore,the statement that intensity is the same for all wavelengths is incorrect.
