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....

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...

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...

In this AC waveforms worksheet, students answer ten questions about AC voltage, frequencies of waveforms and they interpret diagrams of AC voltage.

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.

This lab is designed to have students investigate the relationship between the distance from an explosion and the time it takes the sound of the explosion to reach the observer. The temperature of the air can be changed by changing the...

This lab is designed to help students discover the connections between the linear density of a string and the tension in the string with the speed of the wave along the string. The program can be set with six identical strings or six...
