The film demonstrates how to calculate frequency, wavelength and speed. Variations in how to make each measurement are highlighted, e.g. using the equation v=f λ rather than direct measurements ...

Frequency is a fundamental concept when you're talking about waves, whether that means electromagnetic waves like radio waves and visible light, or mechanical vibrations like sound waves.

A ripple tank can be used to measure and calculate frequency, wavelength and the speed of waves on the water's surface. A ripple tank is a transparent shallow tray of water with a light shining ...
