Detail Page

written by Wolfgang Christian

The Interference in Time and Beats JavaScript Model simultaneously plays two sounds with frequency fA and fB and displays the signal recorded by a nearby microphone on an oscilloscope display. The oscilloscope's horizontal time axis is shown in seconds and the drop-down menu sets the scale. The vertical axis shows the sound amplitude for each sound and the sum of the sounds depending on the check-box settings.

The Interference in Time and Beats 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.

4. The Physical Setting

4F. Motion

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.
