Reflected Waves Diagrams
1. When water waves strike a barrier straight on, they reflect back along the same path.
2. When incident waves strike a barrier at an angle they reflect off at the same angle.
The angle between the normal and the incident wave is called the angle
of incidence.
The angle between the normal and the reflected wave is the angle
of reflection.
The angle of incidence (i) equals the angle of reflection (r).
3. When incident waves strike a parabolic surface, the waves reflect to a focal point.
