Refraction Flashcards
1
Q
When does refraction happen?
A
When light rays deviate (bend) when they pass from one material to another material with a different density
2
Q
What do materials have to be for refraction to happen?
A
Translucent
3
Q
What does translucent mean?
A
Allows light to pass through
4
Q
Why does light deviate from its path during refraction?
A
Because it changes speed when it enters a differenet materia.
5
Q
What is refraction?
A
When light rays travel from one material to another
6
Q
What is the angle of refraction formed by?
A
The refracted ray and the normal
7
