Two light waves having the same waveleng...

Two light waves having the same wavelength `lambda` in vacuum are in phase initially. Then the first ray travels a path of length `L_(1)` through a medium of refractive index `mu_(1)`. Then second ray travels a path of length `L_(2)` throug a medium of refractive index `mu_(2)`. The two waves are then combined to observed interference effects. The phase difference between the two, when they interfere, is

A

`(2 pi)/(lambda) (I_(2)-_(1))`

B

`(2pi)/(lambda)(n_(1)L_(1)-n_(2)L_(2))`

C

`(2pi)/(lambda)(n_(2)L_(1)-n_(1)L_(2))`

D

`(2pi)/(lambda) ((L_(1))/(n_(1))-(L_(2))/(n_(2)))`
