Compressional Pulses Shown With Aid of a Slinky on Lecture Table Top

Demo Description

Lay a slinky spring on the lecture desk top , stretch it out and pinch a segment together and release

Scientific Principles

• Longitudinal or compressional wave propagation.

Equipment

• Slinky

Equipment Location

• Kit (148) aka Kit (147) on [E-3-4]

Instructions

The first photo shows the Slinky nested in the box with the transverse wave spring on [E-3-4].

The second photo shows the Slinky stretched out on the lecture table top ready to propagate some applied compressional pulses along its length.
