Waves transfer ENERGY, not matter
Longitudinal waves: oscillation is parallel to
direction of propagation (energy transfer)
Transverse waves: the vibration is
perpendicular to direction of propagation.
Electromagnetic waves are all examples of
transverse waves.
Frequency = 1/T. Measured in hz.
Medium = what the wave…

The level of interference is to do with the phase relationship between the two waves, to determine
points of intersection. For example, if in anti-phase with similar amplitude then they will cancel out.
Example of a superposition: Stationary waves
The formation of stationary waves is when two progressive waves of…
