MHT CET 2022 Physics question

When the distance of separation between the slit and screen is doubled, the angular separation between fringes in single slit diffraction experiment

(A)first increases and then decreases
(B)remains sameCorrect
(C)increases
(D)decreases

Answer: (B)

Solution

In single-slit diffraction the minima occur at angles given by , so the angular positions (and hence the angular separation between fringes, ) depend only on the wavelength and the slit width . They
