In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound.

This resource explores how vibrating objects produce sound waves. The site contains information and an animation.

Introduce some activities that introduce students to the physics of sound. They will also learn how various instruments produce sound. Included are downloadable pdf worksheets and answer sheets to use.

Light is an example of an electromagnetic wave. Electromagnetic waves can travel through the vacuum of interstellar space. They do not depend on an external medium-unlike a mechanical wave such as a sound wave which must travel through...

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explain how people see images, color and even optical illusions. This tutorial discusses each concept and presents an experiment to try...

In this physics science fair project, the student will use common materials to play back sound from a vinyl record album. The student will investigate what kinds of materials produce the best sound. The Science Buddies project ideas are...

[Free Registration/Login may be required to access all resource tools.] Students investigate behaviors of waves, and explore the Doppler effect phenomenon.

This high school physics lesson focuses on the application of the Doppler effect to sound. Discusses what the Doppler effect is, offers examples of its occurrence, and explains what shock waves and sonic boom are.

This is a rockin' project for guitarists with an interest in the physics behind music. If you have ever wondered why the pitch of the note changes when you fret the string, this project will help you understand by applying basic...

Discover the acoustical properties of brass instruments from this well researched site provided by the University of New South Wales. Everything from lip control to bell shape is discussed as it applies to frequencies and harmonics.
