Two coherent light sources `S_1` and `S_2 (lambda=6000Å)` are `1mm` apart from each other. The screen is placed at a distance of `25cm` from the sources. The width of the fringes on the screen should be

A

`0.0015 cm`

B

`0.025` cm

C

`0.010` cm

D

`0.030cm`

Text Solution

Verified by Experts

The correct Answer is:
A
`beta =(D)/(d) lambda=(25xx600xx10^(8))/(10^(-1)) =0.015 cm`
