This lab is designed to help students visualize distance between two synchronized sources that will lead to constructive and destructive interference.

A model for examining the simultaneity of two events where the relative velocity and the wave source, either light or sound, can be manipulated.

Kids learn the basics of the science of sound, the speed of sound, and volume. What is sound and how does it move? It is a wave made from the vibration of molecules.

This is a five-question quiz related to the passage "The Effects of Ear Canal Acoustics on Hearing Ability."

[Free Registration/Login may be required to access all resource tools.] Discusses what the Doppler Effect is and how it occurs.

[Free Registration/Login may be required to access all resource tools.] What ultrasound and echolocation are, and how sonar and ultrasonography are used.

Physiclips thoroughly presents the concept of interference with animations and film clips. Learn about linear superposition, beats, and consonance in this learning module.

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...

This site is provided for by Michigan Reach Out. Students experiment with the variables of force, pitch and volume after making a drum.

This lesson will describe how the doppler effect is created by moving sound waves. It is 2 of 4 in the series titled "Doppler Effect."

This lesson will describe how the doppler effect is created by moving sound waves. It is 3 of 4 in the series titled "Doppler Effect."

This lesson will describe how the doppler effect is created by moving sound waves. It is 1 of 4 in the series titled "Doppler Effect."

A series of thought-provoking, multichoice questions from the University of Maryland on the topic of oscillations and waves. Equations for calculating the period of motion for masses on springs, pendulums, sounds, and waves on a string...

Using the program "The Music Instinct," available on the PBS website, students will explore the nature of sound vibrations over two class periods.

This site provides an experiment where students create a guitar to discover what variables will change sound.

This site from Architectural Acoustics and Lighting provides a discussion of various factors affecting the acoustics of a given room. Room dimensions, the wavelength of the sound wave, the physical characteristics of the walls, the...

Review key terms and skills for the Doppler effect, including how to interpret wavefront diagrams.

Read about the life and work of this Austrian physicist and philosopher, known for his contributions to physics with the Mach number and the study of shock waves.

Includes exhaustive information and a wealth of activities pertaining to aerodynamics and the physics of flight.
