Question

An incident ray strikes a plane mirror at an angle of 15' with the mirror the angle between the incident ray and reflected ray or what will the angle between the reflected ray and the mirror is​

Answer 1

Explanation:

The angle between the Reflected ray and the mirror will be also 15° .

This is because of law of Reflection.

Angle between Incident ray and the reflected ray = 90° - 15°

= 75°

So angle between Incident ray and Reflected ray = 2 × 75°

= 150°

Answer 2

Explanation:

since incident ray is making an angle of 15° with the mirror so angle of incidence will be 90°-15°=75°

so angle between incident ray and reflected ray will be

75°+75°=150°(angle of incidence =angle of reflection)

and angle between the reflected ray and mirror is 15°
