In Young's double-slit experiment, the slit are illuminated by monochromatic light. The entire set-up is immersed in pur water. Which of the following act cannot restore the oringinal fringe width?

A

Bringing the slit close together.

B

Moving the screen away from the slit plane.

C

Replacing the incident light by that of longer wavelength.

D

Introducing a thin transparent slab in front of one of the slits.

Text Solution

Verified by Experts

The correct Answer is:
d
`beta_(w) = (lambda D)/(mu d)`
we need to increase `beta implies D` increases `d` decreases.
