MHT CET 2024 Physics question

In double slit experiment, instead of taking slits of equal widths, one slits is made twice as wide as the other. then in interference pattern

(A)the intensity of the maxima decreases and the minima has zero intensity.
(B)the intensity of maxima decreases and that of the minima increases.
(C)the intensity of the maxima increases and the minima has zero intensity.
(D)the intensity of both the maxima and the minima increases.Correct

Answer: (D)

Solution

Intensity is proportional to slit width. With equal slits of intensity each: and . When one slit is made twice as wide, the intensities are and : (greater
