Question

Two mirrors are placed at an angle of 100°. A ray incident on mirror 1 is reflected on to mirror 2. If the initial angle of incidence is 70°:
1.What will the angle of reflection be when the ray makes its final reflection?
2.What will the measure of angle be at ‘a’?
3.What is this phenomenon called?

Answer 1

Answer:

Two plane mirrors are inclined at 70∘. A ray incident on one mirror at incidence angle θ after reflection falls on the second mirror and is reflected from there parallel to the first mirror, The value of θ is. Join the 2 Crores+ Student community now!
