If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...

Physics class sure can have its ups and downs! The first in a series of seven interactives from the Waves and Sound series introduces young learners to the concept of wavelength. Scholars work through the interactive to discover the...

Ever wonder why a siren sounds different when it's coming toward you than when it's going away from you? It all depends on the motion of the sound waves! The interactive activity demonstrates how the Doppler effect impacts the motion of...

A simulation for examining the transverse wave motion of a string. Wave variables can be changed using sliders. Includes suggested activities.

Learn about mechanical waves, which transfers energy from one place to another through liquids, gases and solids, with this interactive lesson.

This interactive lesson engages students in noticing the shape of (transverse) waves and learning how to describe and measure the amplitude and wavelength of waves.

[Free Registration/Login Required] Move the points to change the frequency and amplitude of the waves while making the waves transverse or longitudinal according to the labels.

A short tutorial providing general information about waves, their categories, properties and behaviors. Includes several animations and some practice questions with answers.

Students investigate the formation of standing waves, the vibrational patterns associated with the various harmonics, and the difference between transverse and longitudinal standing waves.

In this simulation a series of coupled oscillators in a chain with anchored ends can be investigated for their wave properties.

In this simulation, two strings with different densities are held tautly as a wave pulses along them. Variables can be changed to alter the relative densities of the strings, as well as the type of wave pulse.
