Bending of light as it passes through water?
Yes, light bends as it enters water. This is known as refraction of light. It is the change in direction of a wave due to a change in it's speed. Water has an index of refraction of 1.333 and air has an index of refraction of 1.From Wikipedia:In optics, refraction occurs when light waves travel from a medium with a given refractive index to a medium with another. At the boundary between the media, the wave's phase velocity is altered, usually causing a change in direction. Its wavelength increases or decreases but its frequency remains constant. For example, a light ray will refract as it enters and leaves glass, assuming there is a change in refractive index. A ray traveling along the normal (perpendicular to the boundary) will change speed, but not direction.
Which way does light change direction when it comes out of a block of glass?
out wards
Which way does the light change direction when it goes into the glass block?
bends upward
What happens to a ray of light as it enters and leaves a glass block?
The ray of light gets refracted. Depending on the medium it is entering, it will bend either to or away from the normal. For example, if it is entering a glass block from air, it will bend towards the normal, and if it leaves a glass block and enters air it will bend away from the normal. The amount the ray bends depends on the angle of incidences and the refractive indices of the two mediums, and are governed by Snell's Law.
What can happen to light traveling through a glass filled with water?
Refraction of light occurs when a light pass through a glass that is filled with water. In this process, the light changes direction as it changes transmission medium.
Why does the ray not change direction when it enters the glass at A?
sublimation
When light enters glass from air at an olique angle the wave crests change direction there new direction is what?
The angel of the light ray emerging is called "Angle of Deviation"
When light enters glass from air it changes direction. What is the change of direction called?
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.
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.
If light traveling through air is then passed through glass what is the result?
the light slows in speed and refracts due to glass being denser than air.

What does the path of the sunlight through the air have to do with the climates?
Light is affected by a force called refraction which diverts its path depending on the 'thicknesss' of the medium it is traveling through. For example, a ray of light traveling through air and entering a thicker medium like glass will be refracted and travel in a different direction when it enters the glass. Different climates will create different atmospheric conditions which will make the light travel in different directions.
When light travels from air into a glass slab there is no change in its?
direction
What causes the change in direction when light passes into glass?
REFRACTION
