Answer Details
A person standing waist-deep in a swimming pool appears to have short legs because of refraction. Refraction is the bending of light as it passes through a medium with a different density, such as air and water. Light travels slower in water than in air, so when it enters the water, it bends and changes direction. As a result, the person's legs appear shorter because the light is bending and distorting the image of their legs. This is why objects appear distorted when viewed through the surface of water, a phenomenon known as the "bent-stick" effect.
