The Sound Waveforms JavaScript Model explores the aural texture of four basic periodic waveforms: sine, triangle, square, and sawtooth. The sine waveform has a single frequency and is the building block of other periodic waves by summing harmonics in a Fourier Series. The richness of the sound is called the timbre and is determined by the amplitude of the harmonics in the Fourier sum.
The One-Dimensional Wave Function Superposition JavaScript Model was developed using the Easy Java Simulations (EJS) version 5. It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.

This source code zip archive contains an XML representation of the Sound Waveforms JavaScript Model. Unzip this archive in your Easy Java/JavaScript Simulations workspace to compile and run this model using EJS 5.2 or above. Although EJS is a Java program, EjsS 5.2 creates a stand alone JavaScript program from this source code if the programming language is set to JavaScript.
6-8: 4F/M4. Vibrations in materials set up wavelike disturbances that spread away from the source. Sound and earthquake waves are examples. These and other waves move at different speeds in different materials.
6-8: 4F/M7. Wave behavior can be described in terms of how fast the disturbance spreads, and in terms of the distance between successive peaks of the disturbance (the wavelength).
9-12: 4F/H6ab. Waves can superpose on one another, bend around corners, reflect off surfaces, be absorbed by materials they enter, and change direction when entering a new material. All these effects vary with wavelength.
