Explore in detail the wave front diagrams of stationary and moving sources at both subsonic and supersonic velocities.

This shockwave activity shows the way that waves originate from a single moving source, and provides a link to the same activity using two sources.

Find out about sound waves, and how their graph varies with change of pitch and volume. Check out the experiments which show that sounds are vibrations.

A partnership site between the Science Museum and the Minnesota Orchestra, exploring the science and art of sound by offering performance, activities, and discussion sections.

Learn about acoustics of different instruments, the sound spectrum, standing wave patterns supported by different air columns on this page by The University of New South Wales, Australia .

Learn all about sounds and waves through a graphical-learning based interface in four lessons.

Find out how the doppler effect is used to read the weather, and how it can be used in short term weather prediction.

Power point slides covering wave speed and pulses, energy, superposition, standing waves, doppler effect, Huygen's principle, refraction, interference, and diffraction gratings.

Elucidates traveling and standing waves using diagrams to show harmonic and overtone wave patterns.

Explore synthetic sound and vision with this voice mapping java applet. Sonify the premade images, or make your own.
