MHT CET 2026 Physics question

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

(A)intensity is more for shorter wavelengths
(B)Intensity is same for all wavelengths Correct
(C)Intensity is less for longer wavelengths
(D)A black body emits all wavelengths

Answer: (B)

Solution

A black body emits radiation of all wavelengths, but not with equal intensity: the spectral distribution is a curve that rises to a maximum at a wavelength (Wien's law, ) and falls off on both sides. Hence statement (D) is true; statement (C), that the intensity is low for the
