Prove that for any value of angle i, rays `1 and 2` are parallel

Text Solution

Verified by Experts

PQ and MN are mutually parallel . Rays 1 and 2 are making equal angles`(=/_i)`
from PQ and MN. So, they are muttually parallel.
Important result -two plane mirror kept at `90^(@)` deviate each ray of light by `180^(@)` from its orignal path.
