The refractive index of air is about 1.0003, and of quartz about 1.45, so
quartz is the more "optically dense" medium in this situation.
When light goes from a less dense medium to a more dense medium, it is
refracted toward the normal. The normal is the imaginary line perpendicular
to the surface where the light enters.
It is because the glass has more refractive index than air which makes the light bend more through glass than air.
I think the word you're looking for is "refraction."
Bending of light is caused by a light ray going through different mediums, for example from air into a glass prism.Light would bend when it hits the glass (at an angle) then bend again when it leaves the prism.This is called refraction.The basic cause is the fact that light travels at different speeds in air and glass."Diffraction" can also cause light to bend.Another phenomenon is the bending of light in a gravitational field. This is harder to explain. The reason comes from Einstein's Theory of Relativity.
Light always travels in a straight line. It's direction can be changed, by reflection or refraction, but it does not bend.
Fronts
Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
The ray will bend towards the normal.
It is because the glass has more refractive index than air which makes the light bend more through glass than air.
The light will bend as it passes through.
This is due to the difference in optical density.
light rays bend away from normal as it passes from denser water to rarer air
what happens is that lenses bend light in a way that makes an image
The speed of light slows in water.
the light reflects of the droplets like a prism and bend the rays of light to make a rainbow
Simply put, because the speed of light in the different materials is slightly different.

depends on the angle and the index of refraction
