Because it slows down when entering water.
Refraction occurs when light changes direction as it passes from one medium to another, such as from air to water. This bending of light is due to the change in speed of light as it enters a denser or less dense medium, causing the light rays to change direction.
Laser light bends when passing through water due to a change in the speed of light as it enters a medium with a different refractive index. This change in speed causes the light to change direction, a phenomenon known as refraction.
The light ray will change its direction and bend towards the normal as it enters the water due to a decrease in the speed of light. This is known as refraction.
Refracting light is when light waves pass through a medium such as air, water, or glass and change direction. This change in direction is caused by the change in speed of light as it moves from one medium to another. The amount of bending depends on the angle at which the light enters the new medium.
Light does not bend water; rather, light passing from one medium to another with a different optical density causes the light to change direction, a phenomenon known as refraction. Light changes direction when it moves from air into water due to the difference in optical density, resulting in the appearance of light bending when it enters or exits the water.

It seems to me that, to understand that, you need an understanding of the Huygens-Fresnel principle. Check the corresponding Wikipedia article; it has a nice illustration that shows how refraction is derived from this principle.

When light enters water, it can be absorbed, reflected, or refracted. Some light is absorbed by the water molecules, causing it to heat up. Other light can be reflected back at the surface if the angle of incidence is greater than the critical angle. Finally, light can be refracted as it changes speed while passing from air to water, causing it to change direction.
Water molecules scatter light because they are smaller than the wavelength of visible light. When light enters water, it interacts with the molecules, causing it to change direction and spread out in different directions. This scattering of light is what makes the water appear clear or transparent.
The speed of light decreases when it enters a denser medium and is refracted, such as water or glass. The change in speed causes the light to change direction at the boundary between the two media.
The light will change directions (to be closer to the normal) once it hits the water. This is known as refraction which is a property of light. In this case, you have 2 media (plural form of medium). The two are air and water. The reason it changes direction is because air allows a different speed of light than water. Water is denser which is why light can't travel as fast. This change in the speed of light is what causes the light to change direction once it hits the water. In conclusion, after light hits the water, it will change directions (to be closer to the normal) due to the fact that the medium is changed(from air to water) which results in a change in the speed of light.
The speed of light though substances is slower than the speed of light in a vacuum. As the light passes from air to water it slows and the ray's path is translated towards the normal to the air/water interface slightly.
