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 do different colours of white light bend through different angels with respect to the incident beam of light?
Refraction ! The light is made up of different frequencies that bend at different amounts
Who discovered a prism can bend light?
Unknown, but Newton formalized it and wrote it up.
When do you notice light bending?
Light refracts or bends when it leaves one medium and enters another one (i.e. when it goes from air to water; when it goes from glass to air). This is because the speed of light is different in different materials (light travels in a vacuum at a speed of 3 x 10^8 m/s and is slower in all other mediums). When light slows down (i.e. moves from air into water), the light bends towards the normal; when light speeds up (i.e. moves from water into air), the light bends away from the normal. light is never bent when travelling between media, only refracted. there is research into the bending of light around large objects in space and utilising the bending of electromagnetic waves to create invisible objects.
A light was speeds up as it moves from a more dense to a less dense medium?
yes it will !
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. :)

What causes light rays to bend when they enter a new medium at an angle?
Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.
What is the importance of light energy in photosynthesis?
It speeds up photosynthesis because it acts as a catalyst.
A light was speeds up as it moves from a more dense to a less dense medium?
yes it will !
What is the purpose to how the stems grow?
Yes, they normally grow up and will bend towards light.
