If the angle between the incident ray and a plane mirror is $30 °$ , then what will be the angle of reflection?

Open in App

Solution

According to laws of reflection:
The incident ray, the normal, and the reflected ray all lie on the same plane.
The angle of incidence is always equal to the angle of reflection. i.e i=r.
So, if the angle of incidence is $30 °$ , then the angle of reflection is also $30 °$ .
