A ray of light incident upon a mirror makes an angle of 37.3° with the mirror?

Question

A ray of light incident upon a mirror makes an angle of 37.3° with the mirror. What is the angle between the incident ray and the reflected ray?

Answer 1

The law of reflection gives that the incident light and the reflected light make the same angle with the normal on the surface at the point of contact of ray and the surface.

Now for flat surfaces the total angle is 180 degrees. The angle which the incident and the reflected rays make with the mirror surface would also be equal and is given to be 37.3 degrees each. Thus the required angle between the incident and the reflected rays would be :

angle = {180 - 2.(37.3)} degrees = 105.4 degrees

hope you got it.

Answer 2

180 - (37.3 x 2)
