Angular width (β ) of central maximum of a diffraction pattern on a single slit does not depend upon
(A) Distance between slit and source
(B) Wavelength of light used
(C) Width of the slit
(D) Frequency of light used
Correct option- (A) Distance between slit and source
Explanation:-
For single slit diffraction pattern d sinθ =λ ( d =slit width)
Angular width = 2θ=2sin-1(λ/d)
It is independent of D i.e. distance between screen and slit
