The `xz` plane separates two media `A` and `B` with refractive indices `mu_(1)` & `mu_(2)` respectively. A ray of light travels from `A` to `B`. Its directions in the two media are given by the unut vectors, `vec(r)_(A)=a hat i+ b hat j` & `vec(r)_(B) alpha hat i + beta hat j` respectively where `hat i` & `hat j` are unit vectors in the `x` & `y` directions. Then :

A

`mu_(1)=mu_(2)alpha`

B

`mu_(1)alpha=mu_(2)a`

C

`mu_(1)b=mu_(2)beta`

D

`mu_(1)beta=mu_(2)b`
