Here's a taster:

Basics...
Waves are caused by vibrating particles.
Progressive waves transfer energy.
Waves are called mechanical if they
require a medium to travel through them
(i.e. Sound)
Longitudinal Waves: parallel to the
direction moved by the wave (Sound
waves)
Transverse Waves: at right angles to the
direction being moved in…read more

Here's a taster:

A Transverse Wave
Displacement: Distance from the equlibrium point to a point on
the wave
Wavelength: Maximum distance. One trough and one peak.
Amplitude: Point of Maximum displacement
Period: Time taken for one complete oscillation to occur
Frequency: The number of oscillations that pass through a point
in a given time.…read more

Deriving v=f
1
Okay, so we know that: f
T=
And that wave speed=Wavelengt
h
Period
So we can combine the two and form:
v=f x…read more

Here's a taster:

Phase Difference
The amount that one wave lags from
another.
Measured in degrees
A and B have a phase difference of 180°
C and D Dhave a phase
A difference of 90°
B
C…read more

Progressive Waves and
Energy
Actual `stuff' or matter does not move.
Only the ENERGY is transferred.
Each particle vibrates, this vibrates the
neighbour and so on.…read more
