A ray from air enters water, then through a thick layer of glass placed below water. After passing through glass, it again comes out in air medium. Then final emergent ray will
  1. Bend towards the normal
  2. Bend away from the normal
  3. Suffer lateral displacement
  4. Have the same path as if it had not passed through glass and water

A

B
Suffer lateral displacement
C
Have the same path as if it had not passed through glass and water
D
Bend towards the normal

A light ray passes through a glass slab at an angle from air. The same glass slab is now placed in a tank of water. If the same light ray is now allowed to pass through the glass slab, compare the lateral displacement of the light ray in both the cases.

Q4

Light is incident from air on oil at an angle of 30∘. After moving through oil-1 and another medium; oil-2, it enters glass and then it enters the water. If the refractive indices of glass and water are 1.5 and 1.3, respectively, find the angle which the ray makes with normal in water.
