Aims
• Use real and/or computer animations of water waves to show reflection, refraction, diffraction and interference
• Explain these effects

Refraction is the change in direction of a wave due to a change in its speed.
Reflection is the change in direction of a wavefront at an interface
Diffraction is the apparent bending of waves around small obstacles and the spreading out of waves past small openings.
Interference is the addition of two or morewaves that results in a new wave pattern.
