Reflection of Light

Test yourself

Reflection of Light

Light can be reflected by a plane (flat surface).

Angle of incidence

The angle of incidence is the angle between the incident (incoming) light ray and the normal.
The normal is a line at 90 degrees to the plane.

Angle of reflection

The angle of reflection is the angle between the reflected light ray and the normal.

Law of reflection

The law of reflection states that the angle of incidence = the angle of reflection.
$\theta_i=\theta_r$
