Question

the angle between incident ray and the plane mirror is 30 degree the total angle between the incident ray and reflected ray will be​

Answer 1

Explanation:

Angle of incidence = angle of reflection. 90 degrees is going directly into the mirror. So, 90 – 30 = 60 degrees. The total angle between the incident ray and the reflected ray will be 120 degree.

Answer 2

Answer:

Angle of incidence = angle of reflection. 90 degrees is going directly into the mirror. So, 90 – 30 = 60 degrees. The total angle between the incident ray and the reflected ray will be 120 degree.
