1
Q
What 2 things change and what 1 thing stays the same when waves travel from a medium to another?
A
2 things that change: -speed -wavelength
1 thing that stays the same: -frequency
2
Q
FINISH THE SENTENCE: speed and __________ are directly proportional.
A
WAVELENGTH
3
Q
Why does the frequency of a wave not change when it travels between mediums?
A
because the source is producing the same amount of oscillations (vibrations) per second.
4
Q

A
It can be:
-reflected
-refracted
-absorbed
-transmitted
5
Q
What causes reflection to happen?
A
