Types of waves

Pulse wave: A pulse wave is a non-repeating wave; single disturbance.

Pulse wave

Periodic : Periodic waves are waves that repeat at regular intervals.  they require regularly repeating disturbances in order to be considered a periodic wave.

Periodic wave

Longitudinal:  A longitudinal wave is when several turns of the spring are compressed and released.  The disturbance is in the same direction as the direction of travel.  This wave occurs lengthwise.

Longitudinal wave

Transverse: This wave occurs sideways.  The spring is pulled sideways at a 90 degree angle (right angle) then released.  The wave will travel across instead of lengthwise.
