Angular width (beta) of central maximum ...

Angular width `(beta)` of central maximum of a diffraction pattern on a single slit does not depend upon

A

(a) Distance between slit and source

B

(b) Wavelength of the slit

C

(c) Width of the slit

D

(d) Frequency of light used

Text Solution

Verified by Experts

The correct Answer is:
A
For single slit diffraction pattern `d sin theta=lambda(d=slit wi dth)`
Angular width `=2theta=2sin^-1(lambda/d)`
It is independent of D, i.e., distance between screen and slit.
