Waves and refraction 2
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?
2 Waves are shown crossing from a deep to a shallow water region in a ripple tank.
a Draw the ray diagram as accurately as you can on the wave diagram.
b Measure the angles of incidence and refraction.
Record errors
c Calculate the refractive index (n = sin i / sin r) with an error.
