Extensive information about how waves behave in an elastic medium. Covers different types of waves, their characteristics and behavior, the anatomy of the ear, the speed of sound in different media, the parts of a wave, and wave phenomena.

Provides a simple explanation of how sound waves travel and gives a long list of facts about sound waves.

Online physics lab experiment in which students use resonating waves inside of a closed-end air column to determine the speed of sound. The form allows students to check their answers and receive immediate feedback.

Discusses the characteristics of sound waves and the conditions that affect the speed of sound.

Two wave graphs depicting a sine wave and relating the various characteristics (wavelength, amplitude, frequency, and period) of a wave to each other. The site includes an interactive JavaScript form in which the visitor enters one...
