Question Answer
Does a pencil in water look shorter or longer than it should be? Shorter
Why does a pencil in water look shorter? Because our eyes don't see the refraction of the light coming front the end of the pencil when it goes through a different material (water).
What are the three things the angle of refraction depend on? a) the type of material the light changes to b) the angle it hits the surface at (angle of incidence) c) the colour/frequency of the light
