This is the table of contents for The Physics Classroom unit on sound waves and music. The entire unit is an excellent tutorial on sound with self-check questions throughout. It includes applications and animations.
The following sites provide animations of transverse and longitudinal waves. Some include tutorial information and allow interaction as well.
WavesClick the links in the first row of the table to learn the theory behind transverse and longitudinal waves and to view a video. Longitudinal and Transverse Wave MotionAnimations on this page demonstrate both transverse and longitudinal waves and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is traveling. Transverse Wave and Longitudinal WaveThis Java applet lets you visualize the difference between a transverse wave and a longitudinal wave. Transverse and Longitudinal WavesAnother applet to aid in visualizing transverse and longitudinal waves Wave PhenomenaThis is a Java applet that demonstrates various wave types. It allows you to change parameters of a transverse and a longitudinal wave and observe what happens in each as well as what happens in a mixed wave. |
Mini physics labs/demos are found here. See #23 for instructions for using a Slinky for demonstrating transverse and longitudinal waves.
This site provides links to a number of applets that demonstrate and explain simple harmonic motion.
This Physlet depicts simple harmonic motion of an object on a vibrating spring and on a rotating turntable and shows how a graph of the object's position versus time produces a "wave."
Biography of Christian Andreas Doppler, credited with discovering the Doppler effect
Discussion of the acoustical properties of various musical instruments
(see links related to Doppler Effect)
This site presents the Doppler Effect for sound waves in an animated way to
explain visually what’s happening when you or the sound source are moving,
as well as providing audio samples with movement at different speeds.
This informative page teaches in an animated and audible way the Doppler effect, including the formula for the resulting frequency shift. It also presents the “sonic boom” phenomena in a very visual and pictorial way.
A physics tutorial written for high school students. Includes "Check Your Understanding" quiz.
Covers all components of sound and hearing, including decibels, pitch, loudness, Doppler effect, acoustics, etc.
Table of contents for The Physics Classroom unit on sound waves and music. Lessons 3 and 4 are particularly applicable to Lesson 8.2.
This site deals with how the inner ear or, more specifically, the cochlea separates the frequency components of complex sounds by mechanical means. It includes numerous animations to demonstrate the concepts.
A series of good animations and videos of wave interference, reflection, and diffraction. A text discussion of each is provided.
This page describes how tsunamis differ from other water waves and includes a QuickTime video showing how a tsunami can travel across the Pacific Ocean. Links at the bottom of the page will take you to additional information on tsunamis and their formation.
The following sites provide interesting information on the Tacoma Narrows bridge disaster.
Tacoma Narrows Bridge DisasterA summary with photos and links related to the Tacoma Narrows bridge disaster. It includes a link to a short MPEG that shows the bridge action. Suspension BridgeThis NOVA site describes suspension bridge construction and includes two color video clips of the Tacoma Narrows bridge as it twists and finally collapses. |
Another set of applets depicting superposition:
Ripple TankThis Java applet depicts a ripple tank and the resulting interference pattern from the superposition of two or more waves. You can change the wavelength and even add sources to really complicate the picture. Interference of Sinusoidal WaveformsAnother applet that depicts superposition and interference of two traveling waves, this one showing the sinusoidal waveforms rather than the ripple tank Constructive SuperpositionJava applet that demonstrates constructive interference of two waves. Destructive SuperpositionJava applet that demonstrates destructive interference of two waves. Stationary WaveJava applet that demonstrates a standing wave formed by the interference of two waves.

This applet depicts standing longitudinal waves, which are often difficult to visualize without animation.
