Question

the angle between an incident ray and the mirror is 30° (a) what is the angle of incidence
(b) angle of reflection
(c) total angle turned by the ray of light
​

Answer 1

Answer:

(a) 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. As the angle of incidence and the angle of reflection are equal, both angles equal 60 degrees.
