Refractive Index Flashcards
1
Q
What can happen when a wave hits another medium?
A
1) If it hits the normal, it won’t change direction
2) Sometimes light reflects back
2
Q
What does angle of reflection depend on?
A
Refractive index of object
3
Q
What is the formula for refractive index?
A
Angle of incidence / Angle of refraction
4

How do you remember how a wave refracts?
A
T owards A ir G lass A way G lass A ir
5
Q
What happens when a wave passes into another medium?
A
There is a different density so the wave changes speed and changes direction (refracts)
