What is The spring is moved sideways. The motion of the particles
Longitudin medium (spring) is at right angles to the direction in which the
al Waves? wave travels.
Examples: water waves, light waves
A longitudinal wave is a wave which the vibration of particles
in the medium is along (parallel to) the direction of
propagation of the wave.
The slinky spring moves backwards and forwards to produce
a transverse wave. The particles of the medium (spring) move
along the direction of the wave. The wave that travels along
the spring consists of a series of compression and
rarefaction.
Examples: sounds waves.
