Answer 2

Answer:

1.

• On entering into the glass medium light ray bends towards the normal that is light ray gets refracted on entering the glass medium.

• After getting refracted this ray now travels through the glass slab and comes out of the glass slab by refraction from the other interface boundary.

• Since ray goes from glass medium to air it again gets refracted and bends away from normal.

• The incident ray and the emergent ray are parallel to each other.

• i is the angle of incidence, r is the angle of refraction and e is the angle of emergence.

• Angle of incidence and angle of emergence are equal as emergent ray and incident ray are parallel to each other.

• When a light ray is incident normally to the interface of two media then there is no bending of light ray and it goes straight through the medium.

When a ray of light is incident obliquely on a parallel. sided glass slab the emergent ray shifts laterally . The perpendicular distance between the direction. of the incident ray and emergent ray is called. “lateral shift''.
