prism
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
when light rays mave from one medium to another such as from air to water
light rays bend away from normal as it passes from denser water to rarer air
It does not, it travels as a wave

Light travels under the sea through rays of sunshine that hit the water. Light only travels a few feet under the sea.
what happens is that lenses bend light in a way that makes an image
rays.
Light rays.

Air and water have different refractory periods, meaning that light rays are "bent" differently in air and water. This characteristic is found in all materials light can pass through (oil, glass, etc.) so light bends when it travels between substances all the time.
light travels in straight paths called rays
What happens when light rays travel from water into the air
