Question

what type of waves are produced by slinky

Answer 1

A Slinky can easily demonstrate some basic types of waves, longitudinal, transverse, and standing, as well as several others. A longitudinal wave vibrates parallel to (moves in the same direction of) wave travel (this is a good example of sound waves).

Answer 2

Longitudinal waves are produced in a slinky because the movement of the particles of the medium is parallal to the direction of the movement of the wave.
