A monochromatic beam of light falls on Young's double slit experiment apparatus as shown in figure. A thin sheet of glass is inserted in front of lower slit `S_(2) (lambda = 600 nm` is wavelength of source)

The phase difference between central masxima and 5th minima is

A

`(pi)/(6)`

B

`9pi`

C

`(3pi)/(2)`

D

`8pi +-(pi)/(6)`

Text Solution

Verified by Experts

The correct Answer is:
B
Phase difference `delta = (2n-1)pi = [2(5)-1]pi = 9pi , phi = 9 pi`
