When does refraction happen?
When light rays deviate (bend) when they pass from one material to another material with a different density
What do materials have to be for refraction to happen?
Translucent
What does translucent mean?
Allows light to pass through
Why does light deviate from its path during refraction?
Because it changes speed when it enters a differenet materia.
What is refraction?
When light rays travel from one material to another
What is the angle of refraction formed by?
The refracted ray and the normal
If the light ray bends outward, did it speed up or slow down?
Speed up
If the light ray bends inward, did it speed up or slow down?
Slow down
