In Young's double slit experiment the intensity of light at a point on the screen where the path difference `lambda` is K. The intensity of light at a point where the path difference is `(lambda)/(6)` [`lambda` is the wavelength of light used] is

A

`K//4`

B

`K//3`

C

`3K//4`

D

`K`

Text Solution

Verified by Experts

The correct Answer is:
C
`K = I_(0)cos^(2)(pi)rarr(1) , I = I_(0)cos^(2)((pi)/(6))rarr(2)`
