Refraction Flashcards
1
Q
If the speed is reduced, which direction is the refraction?
A
Towards the normal(eg. Air to glass)
2
Q
If the speed is increased, what direction is the refraction?
A
AwY from the normal(eg. Glass into air)
3
Q
What happens when waves cross a boundary between different substances?
A
The wave changes speed and wavelength.
4
Q
What does the change in the speed of the waves cause?
A
Change in direction.
5
Q
If the wave is travelling along a normal, will it change direction?
A
No it won’t
6
Q
Which light colour refracts the most?
A
Violet light
7
Q
Which colour of light refracts the least?
A
Red light
8
