This page features an animated image and a discussion of the forces of mechanical waves. The animation shows how a tuning fork works by using longitudinal waves to create alternating high and low pressure areas.
This tutorial is part of The Physics Classroom. This web site also includes interactive tools to help students with concepts and problem solving, worksheets for student assignments, and recommendations for simple introductory laboratories.
