The width of the diffraction band varies...

The width of the diffraction band varies

A

inversely as the wavelength

B

directly as the width of the slit

C

directly as the distance between the slit and the screen

D

inversely as the size of the source from which the slit is illuminated.

Text Solution

Verified by Experts

The correct Answer is:
C

Width of the diffraction band, `beta = (D lambda)/(a)` where D = distance between slit and the screen, a = width of the slit `lambda =` wavelength.
