Wavespeed
Depends on
Type of wave (e.g. light vs. sound)
Properties of the wave's medium
speed of particles (temperature)
Distance between particles (solid vs. liquid vs. gas)
Size of particles (Oxygen atoms vs. Helium atoms)
Does not depend on frequency or wavelegth, despite the equation v = f (lambda)
Interference
Two waves CAN occupy the same space at the same time. When they do, they add together.
