Wave on a String
The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Doppler Ducks
The study of waves is not a quacking matter! Watch as a duck manipulates the behavior of its waves through its motion. Graphs show the frequency and wavelength of the waves.

Waves - Case Studies
What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...
Curated OER
AC Waveforms
In this AC waveforms worksheet, students answer ten questions about AC voltage, frequencies of waveforms and they interpret diagrams of AC voltage.

Rocking the Boat
Sometimes it's okay to rock the boat! Science scholars manipulate wave properties using a fun interactive. Part of a larger playlist that dives into waves and sound, the lesson helps users work their way from apprentice to wizard by...

Stow Lake
Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

Physics Aviary: Wavelength Lab
This lab is designed to have students investigate the relationship between the speed of a wave, the frequency of the wave and the wavelength of the wave. Students can vary wave speed and frequency. Each of these should be varied while...
Georgia State University
Georgia State University: Hyper Physics: Speed of Sound
Physics tutorial on measuring the speed of sound in dry air. An interactive form allows the student to practice solving problems involving the temperature dependence of the speed of sound.
