Question

A ray of light strikes a plane mirror at an angle of incidence equal to 35 degrees. The angle between the incidence ray and the reflected ray is?

Answer 1

The answer of this question is very easy. But before answering this question please understand the basic thing of light.

The ray that is coming in is called the incident ray and the angle that it makes with an imaginary line perpendicular to the surface of the mirror is called the angle of incidence.

And the angle between the outgoing ray (reflected ray) with this imaginary perpendicular line is called the reflection angle.

The angle of incidence = angle of reflection

here, we have -

angle of incidence = 35 deg.

Therefore, the angle between the incidence ray and reflected ray = 35 + 35 = 70 deg.
