Question

if the angle of incidence and angle of emergence of a light ray falling on glass slab is i and e respectively then prove that; i=e.​

Answer 1

Answer:

according to the second law of reflection. angle of incidence=angle of reflection.

thus, the angle of emergence of a light ray falling on glass slab is the angle of reflection.

thus , i=e

Answer 2

Answer:

according to the second law of reflection. angle of incidence=angle of reflection.

thus, the angle of emergence of a light ray falling on glass slab is the angle of reflection.

thus , i=e
