The change in wave speed causes refraction sinv1/v1 = sinv2/v2.
The wavelength changes. Whether it increases or decreases depends on the index of refraction of both materials.
Refraction occurs when light travels from one medium to another having different optical densities.
Refraction occurs because the speed of the wave varies in different materials,sin(I)/V(I) = sin(T)/V(T)
When a toy car travels from a plain floor to the grass lawn we see that it deflects.Similarly light too bends when it changes its medium.This bending can be seen at the boundary of the two mediums that separates them.
The velocity of light travelling through a material relates to the index of refraction of that material. In this group, air has the lowest index of refraction, follow by water, fused quartz, and crown glass. This means like travels the fastest through air, then water, then fused quarts, and finally glass.

Light does not refract via a single material. Refraction occurs when light passes from one material into another of a different density. It is the amount of difference in densities that causes the refraction. The greater the difference the greater the refraction. I believe that the densest material would be diamond, so light passing through a diamond and into a vacuum would seem to be the greatest difference, causing the greatest refraction.
True

When light travels at right angles into a transparent object (i.e. angle of incidence is zero), no refraction occurs.
it depends on the kind of material medium it occurs on. and it's wavelenght.

light passes trough the cornea then through the pupil and opening created by the iris, then the light passes through the lens, then travels along the aqueous humerous then arrives at the retina; the retina changes teh light into electrical impulses and send them trough the optic nerve then to the brain where an image is perceived.
