MHT CET 2023 Physics question

The diffraction fringes obtained by a single slit are of

(A)equal width
(B)equal width and unequal intensity
(C)unequal width but equal intensity
(D)unequal width and unequal intensityCorrect

Answer: (D)

Solution

In the Fraunhofer single-slit pattern the central maximum is the brightest and its angular width () is twice that of each secondary maximum (), so the fringes do not all have the same width. The intensities of the secondary maxima fall off rapidly (), so the
