This learning episode, from the Institute of Physics, introduces the basic idea of superposition of waves, explaining what happens when two or more waves meet.
The activities include:
• recapping students’ knowledge and understanding of waves
• demonstration of waves using a rope
• discussion of waves as ripples in a pool and how this demonstrates superposition
• considering phase difference and superposition
• adding waves graphically
