Question

Quizplus · Accepted Answer

When light passes from air to water, it refracts or bends at the surface because the speed of light changes as it enters the water. This causes a change in the direction of light rays, which can make objects look distorted or displaced. In the case of a person standing in waist-deep water, the light rays passing through the water will bend as they enter and exit the water, causing the person's legs to appear shorter than they actually are. This is an example of refraction.
