Question

A ray of light enters a room, falls on a plane mirror (m) and is reflected back as shown in fig. D. During this reflection, if the angle of incidence (i) formed is equal to 60˚, the angle of reflection (r) will be: a) 30˚ b) 120˚ c) 15˚ d) 60˚​

Answer 1

Answer:

60˚​

Explanation:

Answer 2

Answer:

the answer is 60° ....The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 - 30 = 60 degrees
