A unit vector along the incident ray of ...

A unit vector along the incident ray of light is `hat(i)`. The unit vector for the corresponding refracted ray of light is `hat(r ).hat(n)`, a unit vector normal to the boundary of the medium and directed towards the incident medium. If `mu` is the refractive index of the medium, then snell's law (second law) of refraction is

A

`hati . Hatn = mu (hat r.hatn)`

B

`hati xx hatn = mu (hatn xx hatr)`

C

`hati xx hatn=mu (hatr xx hatn)`

D

`mu (hati xx hatn) = hatr xx hatn`
