What is a glass slab?
it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.
Why do objects look distorted under water?
A ray of light will change direction when going out of water, into the air. This is called "Refraction".A ray of light will change direction when going out of water, into the air.

Which property of light is illustrated when the ray enters the pond?
refraction
What happens when a ray is directed at a glass box?
when a ray box is shown at a mirror it reflectes
What happens to the direction of a light wave when it passes from a less dense medium such as air into more dense medium such as glass?
the light 'beam' (if you like) will slightly change direction this is bending light, light only travels in straight lines but due to the shape of the glass it changes direction when the beam exits the glass its should go back to its shape of ligh beam .
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 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 is the name given to the change in direction of the ray of light as it enters a prism?
Refraction
When a ray enters or leaves a glassblock It may change direction?
I think its reflection.
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.
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.
When a ray of light from air enters to glass what happens to velocity?
it decreases
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.
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.
What happens to the direction of a light ray as it travels from glass to air?
the light 'beam' (if you like) will slightly change direction this is bending light, light only travels in straight lines but due to the shape of the glass it changes direction when the beam exits the glass its should go back to its shape of ligh beam .
What happens to the direction of a light ray as it travels from glass into the air?

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.
