Amplitude is...
... The height of the wave(A) (M)
4 of 9
Wavelength...
...the distance from one point on a wave to another identicle point on the wave.
5 of 9
Frequency is...
...the number of waves that pass a point in one second
6 of 9
Reflection is...
...the bouncing of a wave off a surface
7 of 9
