A light was speeds up as it moves from a more dense to a less dense medium?
This is an example of refraction. When light moves from a more dense medium to a less dense one, it speeds up, causing it to bend away from the normal.
Why does tha refracted light bends towards the base of prism?
When light enters a denser medium from a rarer medium, it slows down, causing it to bend towards the normal. As the light exits the denser medium into the rarer medium, it speeds up and bends away from the normal. This change in speed and direction is why refraction occurs in a prism.
Why does light change direction in a glass block?
It doesn't it it hits it straight on. But - Light slows down when passing through glass (as compared to air), so think of a light beam as a bunch of soldiers walking side by side. If the ones at on one end of the line slow down then their path will bend.
Why does light split up in a prism?
Light splits up in a prism because different colors of light travel at slightly different speeds through the prism due to their different wavelengths. This causes the different colors to refract, or bend, at different angles, resulting in the separation of white light into a spectrum of colors.
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.

How do bend light?
lenses bend light by having the light pass through the glass(or whatever material) of the lense in which the light will slow down. As the light enters the glass the very first part of the ray will slow down alowing other parts to catch up. This makes the light bend towards the normal (perpendicular to side of glass). As the light leaves the glass the oposite occurs. The light that leaves the glass goes faster leaving other parts behind and bending it away form the normal. How much the light bends depends on the shape of the lense the material of the lense and the angle that the light comes in at.
When white light is refracted the amount that the light bends depends on the light's?
The medium. The denser the material the more light slows down as it enters. As it slows down the angle of refraction will be smaller than the angle of incidence and the ray will bend towards the normal. How much it bends will depend in the difference in speed which depends on the density of the material. The ratio between the 'speeds' is the refractive index. Look up refractive index and Snell's law.

How is optical density related to refraction?
As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal. But why does the light appear to bend and refract? Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal. I hope this helped. :)
Name given to the process whereby white light is split up into a spectrum?
The process is called dispersion, where white light is separated into its component colors, creating a spectrum. This phenomenon occurs due to the different speeds at which each color of light travels through a medium, causing them to bend at different angles.
When white light is refracted the amount that the light bends depends on what?
The medium. The denser the material the more light slows down as it enters. As it slows down the angle of refraction will be smaller than the angle of incidence and the ray will bend towards the normal. How much it bends will depend in the difference in speed which depends on the density of the material. The ratio between the 'speeds' is the refractive index. Look up refractive index and Snell's law.
Why the ray of light bends away normal or towards normal when it passes from one medium to another?
When light travels from a less dense medium to a denser medium, it bends towards the normal. This is because light slows down in a denser medium, causing it to change direction. When light travels from a denser medium to a less dense medium, it bends away from the normal as it speeds up in the less dense medium.
Perspex has a higher refractive index than air Light entering air from perspex will?
bend towards the normal as it enters air from perspex due to the change in refractive indices. This is known as refraction and occurs whenever light passes from one medium to another with a different refractive index.
