Interference in Time and Beats JS Model
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.
