Best Answer

refraction of light produces the shallow swimming pool illusion. As you look down at a pool, you are seeing light that has changed angle as it moves out of the water and into the air. Specifically, light moves faster through air than water. Light coming up from the bottom of the pool refracts down to arrive at your eyes at a shallower angle. You see the bottom of the pool a little higher and farther away than it actually is.

This is because the light that falls upon the water surface does not continu in the same direction as it hit the surface: the light refracts. Since the light is refracted along the water surface, the light travels a larger distance, giving rise to the perception of a larger depth.

There is a reflection in the pool that makes it seem shallow.

Light from objects under the water comes up into the air and in so doing, bends a fair amount, fooling your eyes into seeing the objects as closer to the surface than they really are.

Why do rivers appear shallower than they really are?

Let us consider an object 'O' at the bottom of a river/swimming pool. Light speeds up as it travels from water to air. So, the ray is bent away from the normal. As a result for an observer on the shore, it appears as if the rays are coming from a point 'I', which is just slightly above the bottom of the surface That is why rivers and swimming pools seem shallower than they really are.
