Description

Reflection of Light

When light strikes a surface, it can either be reflected or absorbed. The angle at which it strikes the surface is known as the angle of incidence, while the angle at which it reflects off the surface is known as the angle of reflection.

  1. a

    State the relationship between the angle of incidence and the angle of reflection.

    Aim for approximately 1 distinct marking point.
