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.

When a ray of light passes from water to air speed increases?
Yes. The speed of light in water is approximately 2/3 the speed of light in air.
In vision light rays first pass through the?
Lens
Do gamma rays pass through water?
Yes, they do.
What happens to to light waves as they pass through water?
if the light rays are coming from air, they will be refracted at the water boundary towards the normal. refraction occurs because the light rays change speed at the boundary as they travel faster in a less dense medium (air) than they do in a more dense medium (water). hope this helps. alert me if it doesn't :)
What are the functions of concave lens?
To diverge the light rays that pass through it.
When a ray of light passes from water to air speed increases?
Yes. The speed of light in water is approximately 2/3 the speed of light in air.
What does a lens do?
It bends the rays light which pass through it.
What happens to light rays as they pass to one medium to another?
As light rays pass from one medium into another, they bend (or "refract"). This can be easily seen by trying to poke at something under water from above the surface (for example, aim a drinking straw at a target in a glass of water). This refraction is a consequence of the change in direction due to the wave-qualities of light, as the speed of the light is affected by the change of medium.
What is anything that will not allow light rays to pass through?
coal
