The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees

Answer:120°
Explanation:
Angle between incident ray and the plane mirror=30°
Angle between plane mirror and the normal=90°
Angle of incidence=90°-30°
= 60°
Angle of reflection=60°[Because of laws of reflection]
The total angle between the incident ray and the reflected ray=Angle of incidence+Angle of reflection
=60°+60°
=120°
