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 is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
depends on the angle and the index of refraction
Simply put, because the speed of light in the different materials is slightly different.
Light travels faster.
Because of light refraction. Water has a larger refractive index than air, making light that travels to your eye bent. Shabbir Tareen Quetta.

The reason for the pole appearing bent when put inside a glass of water is refraction. When a ray of light travels through one medium to the other, it tends to bend or deviate from its original path. Thus a light ray in this case, travels from the air through water, and then again through air and reach the eyes. Thus, the light ray deviates from its original path causing this phenomenon.
Light always travels in a straight line. It's direction can be changed, by reflection or refraction, but it does not bend.
Water is denser than air . Hence light travels faster in air than water.
The ray will bend towards the normal.
light rays bend away from normal as it passes from denser water to rarer air
