Figure 3 shows a clown fish, Nemo, looking at point B. It sees the fisherman's net appearing as if it were at A.

Given that angle c is the critical angle for the air-water boundary, calculate the refractive index of the water.

This question uses a figure or table from the paper — you'll see it when you practise.
