Question

4. In some parts of the world people use spears in order to catch fish. Quite often when people try to do it for the first time they will miss, even if the fish is only a meter or so away. They quickly learn to not aim at the fish but just slight away from it. i) Why do you think this is?

Answer 1

The fishes are to be aimed slightly away from their orignal position to hit them because of the phenomenon of refraction.This is all to do with the refraction of light and real and apparent depth.

As the light from the fish leaves the water it bends away from the normal . This makes the fish appear to be nearer to the surface when actually they are not. This is the reason why people do so.
