Answers

Answered by anubhav35

30 degree as in 1st mirror

VenkatSwaraj: no

VenkatSwaraj: if the angle of reflection is 30 degree there is no rule that it will fall on second mirror which is perpendicular to the first mirror with same angle.

VenkatSwaraj: show me the proof

VenkatSwaraj: the answer is 60 degree
