Longitudinal waves carry energy through air, water, and solids. They compress and expand the medium in the same direction as the energy is transferred.

Everyday examples and laboratory experiments explain and demonstrate the concept of waves as they relate to physics. Three segments cover the characteristics of transverse and longitudinal waves and the reflection and refraction of waves. Complex physics is made clearer by the lab demonstrations.
A wave carries energy from one point to another through a medium. Types of waves include light, sound, electromagnetic, mechanical, transverse, and longitudinal. Explores a wave's characteristics, such as amplitude, frequency, and wavelength. Also presents the four ways waves interact with mediums. Defines terminology as it is introduced. Quiz after summary.
When an earthquake hits, it sends seismic waves through the ground. Find out about seismic waves in this animation.
Waves are all around. They are a disturbance that travels through space and matter transferring energy from one place to another. Find out about the nature, shapes, and impacts of waves in this animation.
