What is meant by the phrase normal to the surface?
Normal to the surface is a vector which is perpendicular to that surface
Why perpendicular light rays don't refrect through a medium?
As it is parallel to the normal to the surface, the angle of incidence is zero and hence the angle of refraction also has to be zero. Hence no deviation and no refraction.
When measuring the angle of incidence and angle refraction the imaginary line drawn perpendicular to the surface at the point of incidence is called the?
normal.
Does meaning of normal change when representing refraction?
No
What word means the ray 'bouncing off a surface'?
Refraction

When light passes from a medium with a high index of refraction into a medium with a lower index of refraction which direction does the light bend?
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.

It's called the normal.
What are the laws of refraction?
angle of incidence of a wave hitting a surface equal the eagle of refraction.
What are two angles formed by the beam of light as it bends its way into and out of the prism?
The angle of incidence and the angle of refraction, both measured relative to a normal to the surface
What is reflection and refraction of light?
Reflectivity isn't a property of light, it's a property of the surface that reflects the light. It is the proportion of the energy in an incoming light beam which when it hits the surface is reflected rather than absorbed.
Your pool water comes out clear but you can't see the bottom what's wrong?
It's because of total refraction. The light coming from the bottom of the pool cannot escape the separation surface if the angle is more than a specific value. More precisely sin(angle) > (n2/n1) where the angle is that between the perpendicular to the surface and the ray, n1 is the refraction index of water and n2 is the refraction index of air. I hope this is what you meant.
