Refraction of light takes place where a beam of light passes from one medium to another and the speed of light in those two media is different.
They don't demonstrate light; they assume that you have light in the first place.
Refraction is the phenomenon which allows light to pass from one medium into the other. But opaque object will not allow light to pass through. So refraction becomes impossible in case of opaque objects.
By setting up a configuration where either reflection or refraction takes place.
It happens when light enters different mediums, causing it to 'shift speeds'
Refraction. White light is a mix of colors in the first place; these colors have different indices of refraction. That is, when moving from air to glass, as in a prism, they will bend at slightly different angles.
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.

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.

if the ray of light enters the water from air,refraction takes place and the ray of light will bend towards the normal due to higher optical density.
