A plane mirror makes an angle of \(30^{\circ}\) with horizontal. If a vertical ray strikes the mirror, find the angle between mirror and reflected ray
Open in App
Solution
The correct option is C 60∘
The angle between mirror and normal is \(90^{\circ}\).Reflected ray (RR) makes an angle of \(30^{\circ}\) with the normal.
Therefore the required angle between mirror and reflected ray will be \(\theta =90^{\circ}-30^{\circ}=60^{\circ}\).
The angle between mirror and normal is \(90^{\circ}\).
Reflected ray (RR) makes an angle of \(30^{\circ}\) with the normal.
Therefore the required angle between mirror and reflected ray will be \(\theta =90^{\circ}-30^{\circ}=60^{\circ}\).
