Progressive and Standing Waves

What is a progressive and standing wave?

In this post, we conduct an investigation to distinguish between progressive and standing waves, as a part of the Prelim Physics course under the module Waves and Thermodynamics and sub-part Wave Behaviour.  A progressive wave is a wave that travels continuously in a medium in the same direction without a change in amplitude, while a standing wave is a wave in which the position of the maximum and minima do not travel, but remain in place.

The following two videos demonstrate the properties of progressive and stationary waves.
