Answers

1 Waves made with a straight roller are shown crossing a ripple tank. What can you say about the depth of the water in the tank?   The water is deep along the top of the tank and shallow along the bottom.

2 Waves are shown crossing from deep to shallow water in a ripple tank. a The ray diagram is drawn on the wave diagram. b The angles of incidence and refraction are.... angle i = (83±1)° angle r = (65±1)° c The refractive index n is.... 1.10 ± 0.01

3 The waves are drawn after reflection.
