The observer 'O' sees the distance `AB` as infinitely large. If refractive index of liquid is `mu_(1)` and that of glass is `mu_(2)`, then `(mu_(1))/(mu_(2))` is :
.

If refractive index of core & cladding are mu_(1) & mu_(2) respectively then :

If refractive index of core & cladding are mu_(1)&mu_(2) respectively then :

A light ray travelling in a medium of refractive index mu_(1) is incident on a parallel faced glass slab making an angle of theta with the glass surface. The refractive index of the medium on the other side of the glass slab is mu_(3) ( gt mu_(1)) . Find the angular deviation suffered by the light ray.

A double convex lens, lens made of a material of refractive index mu_(1) , is placed inside two liquids or refractive indices mu_(2) and mu_(3) , as shown. mu_(2)gtmu_(1)gtmu_(3) . A wide, parallel beam of light is incident on the lens from the left. The lens will give rise to
