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) to (1)`
`I = I_(0) cos^(2) ((pi)/(6)) to (2)`
