Light will undergo refraction, and the light rays will bend towards the normal, because it is entering an optically denser medium. In this case, the angle of refraction will be smaller than the angle of incidence. In addition, the speed of light will be reduced when travelling in water.

2) unless perpendicular, it bends (and each color bends slightly differently).
3) it's intensity drops as it is absorbed by the water.

How does the direction of a ray of light change as it passes from air into water?
When a ray of light travels it is in a wave and when it enters from air to water it becomes more dense and harder to move so the waves are refracted.
When a ray of light from air enters to glass what happens to velocity?
it decreases
How does light rays behave when it pass from air to water?
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.
How do you explain that the pencil appears broken in the glass of water?
A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".A ray of light changes direction when it gets out of the water, and into the air.

What is the velocity change when the ray of light passes from air to glass?
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
What happened to the ray of light when it entered the water?
if the ray of light enters the water from air,refraction takes place and the ray of light will bend towards the normal due to higher optical density.
How does the direction of a ray of light change as it passes from air into water?
When a ray of light travels it is in a wave and when it enters from air to water it becomes more dense and harder to move so the waves are refracted.
When will a light ray be bent closer to the normal?
When it enters a medium with a higher index of refraction (i.e. air --> water)
When a ray of light from air enters to glass what happens to velocity?
it decreases

When a ray of light from air enters to glass what happens to wavelength?
It will not change. Glass slows light but does not change it frequency.
What does speed change when a ray of light leaves air and enters a piece of glass?
The speed of light slows down ... in general, the denser the material, the lower the speed of light. (For example : air to water to glass.) The maximum speed is in a vacuum.
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend if it enters a glass block perpendicularly.
What is the velocity change when the ray of light passes from air to glass?
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
When light passes from water to air the light rays are what?
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.
What happen to light passes from air to water?
As a ray of light travels from the air to water, refraction occurs. This is because the light has entered a medium where its speed is different. The light is bent towards the normal as the edge of the ray that first touches the water is slowed. Picture yourself driving a car when you drive through a puddle on the right edge of the road. The right tire enters the puddle and, since it can't travel as swiftly in water, it slows, causing the car to turn slightly to the right.
