It demonstrates wave motion through various experiments, including using a slinky and a wave machine. Key concepts include the relationship between wave speed, wavelength, and frequency ...

Have students take turns compressing 10–20 coils and then releasing them rapidly while they hold the end of the slinky, making sure to watch the energy wave travel the length of the slinky.

The movement of the coils of the slinky and the energy are parallel. However, none of the particles are transported along a longitudinal wave. Instead, they move backwards and forwards as the wave ...
