Question

The diagram in figure shows an incident ray $\text{AO}$ and the normal $\text{ON}$ on a plane mirror. Draw the reflected ray. State the law you used to draw the direction of reflected ray.

Answer 1

The law of reflection of light is used to draw the direction of reflected ray. This law states that the angle of incidence is equal to the angle of reflection.
$\angle i=\angle r$
$\angle r={60}^{\circ }$
