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

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.

At this site, the student can find out thermophysical properties of different fluids and gases.

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.

Do you need to know a specific value of a specific quantity for any given substance? If so, this is the place. Find the heat capacity, heats of vaporization and fusion, and much more from this page.

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...

A biographical sketch of Christian Doppler (1803-1853), the Austrian mathematician whose study on the dependence of pitch upon the relative speed of source and observer resulted in the Doppler effect.
