Question

O3) Identify the
phenomenon and mirror in
the given figure
Incident ray
Original
direction of
the toy
Reflected rey​

Answer 1

ON is normal on the plane mirror at point O

ON is perpendicular on a plane mirror

Angle of incidence ∠i= ∠AON

And angle of reflection ∠r = ∠BON

Since

∠i = ∠r

∠AOB = 30

∠AON +∠BON = 30

∠i + ∠i -30

2∠i = 30°

∠i = 30/2

∠i = 15°

the angle of incidence = the angle of reflection = 15°
