Here's a taster:

Waves move energy from one place to
another. In a progressive wave the wave
front moves through the medium.
· Transverse waves are waves where the
displacement of the particles in the medium
is perpendicular to the direction the wave is
travelling in.
· Longitudinal waves are waves where the
displacement of the particles in the same
direction as the wave is travelling in.…read more

Here's a taster:

Transverse waves
· The displacement of particles is perpendicular to
the direction of energy transfer.
· Eg: light and secondary seismic waves.
· For transverse waves in matter, the
displacement of the medium id perpendicular to
the direction of propagation of the wave.
· A ripple on the surface of a pond or a wave on a
string are easily visualised as transverse waves.…read more

Here's a taster:

Longitudinal waves
· Longitudinal waves are waves that
propagate parallel to the transfer of
energy.
· Eg: Sound waves and waves in a
stretched spring are longitudinal waves. P
waves (relatively fast moving longitudinal
seismic waves that travel through liquids
and solids) are also longitudinal waves.…read more
