Q

Reflection

A

When a wave is travelling through a medium and it hits the surface of another medium, it bounces back. The waves are reflected from the surface at the same angle they strike it.

When a wave passes from one medium to another medium, the direction of the wave changes. When the waves slow, they change direction.

A

The waves bend round the side of an obstacle, or spread out as they pass trhough a gap. Wider gaps produce less diffraction.
