Vedclass · Answer

(B) black body is an ideal body that can emit and absorb all frequencies of electromagnetic radiation. Thus,statement $(A)$ is correct.The frequency distribution of the emitted radiation from a black body depends solely on its temperature. Thus,statement $(B)$ is correct.For a black body at a given temperature,the intensity of emitted radiation varies with frequency,showing a characteristic curve that passes through a maximum value. Thus,statement $(C)$ is correct.According to Wien's displacement law,as the temperature of a black body increases,the peak of the intensity distribution curve shifts towards higher frequencies (or shorter wavelengths). Thus,statement $(D)$ is correct.Since all statements $(A)$,$(B)$,$(C)$,and $(D)$ are correct,the number of incorrect statements is $0$.
