Light of wavelength `lambda_(0)` in air enters a medium of refractive index n. If two points A and B in this medium lie along the path of this light at a distance x, then phase difference `phi_(0)` between these two point is

A

`phi_(0) =1/n(2pi)/(lambda_(0))x`

B

`phi_(0) =n(2pi)/lambda_(0)x`

C

`phi_(0) =(n-1)((2pi)/lambda_(0))x`

D

`phi_(0) = 1/(n-1)(2pi)/(lambda_(0))x`
