In Young's double slit experiment, the intensity of light at a point on the screen where the path difference is `lambda=l`. The intensity of light at a point where the path difference becomes `lambda//3` is

A

`K//4`

B

`K//3`

C

`K//2`

D

`K`

Text Solution

Verified by Experts

The correct Answer is:
A
`K=I_(0)cos^(2)(pi)rarr(1)`
`I=I_(0)cos^(2) ((pi x)/(3))rarr (2) theta = (2pi x)/(3)`
