Pulse Wave:
A wave that does not repeat and only occurs with a single disturbance.
Periodic Wave:
A wave that occurs at repeated intervals and has repeated disturbances.
Transverse Wave:

Longitudinal Wave:
When the springs are compressed to one side and then are let go to allow the energy to travel lengthwise through the slinky.
