Let's assume that the light ray is entering the water from above so it isn't also passing through the wall of a container.
As the light ray enters the water it will be refracted toward the vertical. This means that if it is already vertical, it won't be refracted at all. The change in the angle of the light ray as it enters the water is related to the refractive indices of the air and water. Let's call the angle between the light ray and the vertical in air theta1 and the angle between the light ray and the vertical in the water theta2. Then, according to Snell's law:
{sin(theta1)/sin(theta2)}={n2/n1}
where n1 is the refractive index of air, and n2 is the refractive index of water.
The speed of light in water is slower than in glass because glass has a higher refractive index. When light rays pass from water into glass, they slow down due to the denser medium, causing them to refract towards the normal. Glass slows down light more than water because of its higher optical density.
Light rays can travel through air, vacuum, and transparent materials such as glass or water. These materials allow the propagation of light by allowing the rays to pass through with little to no absorption or reflection.
Reflection and refraction are two behaviors of light that are commonly modeled using light rays. Reflection occurs when light rays bounce off a surface, while refraction occurs when light rays bend as they pass from one medium to another, such as air to water.
Blue light rays will bend the most and red light rays will bend the least when entering a drop of water simultaneously. This is because blue light has a shorter wavelength, leading to stronger interactions with the water molecules. Red light, with a longer wavelength, experiences less refraction.
If you are referring to a situation in which light is reflected from water back into the air, then the light rays are "polarized." All light rays travel in straight lines, but polarized light is light that enters a medium from many directions, but are exited (reflected or refracted or merely cut out, like in sunglasses) in one direction.

It bends the rays light which pass through it.
Light rays do not pass through opaque objects such as walls, thick metals, or dense stones. These materials absorb or reflect light rather than allowing it to pass through.
In vision, light rays first pass through the cornea and then through the lens before reaching the retina at the back of the eye.
Yes, gamma rays can pass through water, but some of the energy of the gamma rays will be absorbed or scattered as they interact with the water molecules. The amount of absorption or scattering depends on the energy of the gamma rays and the thickness of the water.
