Wave Interference 3

Java

This applet demonstrates superpositions of wave forms which you draw yourself.

Basic operation:

  • The applet starts out running showing the interference of two sinusoidal waves.
  • The several checkboxes have obvious meanings. You can choose to see notes, wave 1, wave 2, and the sum of both waves.
  • Click the 'Draw wave 1' button. A rectangle will appear to the left. Drag your mouse through the rectangle and draw a waveform. Since the animating applet makes it difficult to see the mouse on some systems, a small circle appears to help you with your positioning.
  • Click the 'Draw wave 2' button. A rectangle will appear to the right. Drag your mouse through this rectangle to draw the second waveform.
  • Click the 'Run' button and the hand drawn waves will be set into motion.
  • If you click the 'You' button at the top right, then you can drag your mouse across the applet horizontally to slowly and carefully examine the interference.
