Chapter 5 - EM Waves - Refraction Flashcards
1
Q
What happens when a wave goes into a new material (medium)?
A
It changes speed - which causes its wavelength to change and its direction to change to (frequency does not change)
2
Q
What happens when the slows down in a new material?
A
It will refract towards the normal
3
Q
What happens when the speeds up in a new material?
A
It refracts away from the normal
4
Q
What is the surface that light refracts off called?
A
Interface
