Question

Q.26. In a laboratory activity, a student traced the path of a light ray through a rectangular glass slab. He measured the angle between the light ray and the edge of the glass slab and found it is 30.. Draw a ray diagram to show the path of the light ray through the glass slab for the measurement given and mark angle of incidence, angle of refraction and angle of emergence. What is the value of angle of emergence?

Answer 1

Angle of emergence is equal to angle of incidence.Here angle of emergence is equal to 60.Hence angle of emergence is equal to 60
