Applets by Daniel Roth - Lissajous Figures

(c) 1999 by Daniel Roth, FiPS, Department of Physics, University of Kaiserslautern, Germany

Java Applet

Two linear and perpendicular to each other oriented oscillations can be added to create a two dimensional oscillation. The path which describes this oscillation forms a Lissajous figure. This figure depends on the amplitude, the frequency and the phase difference of the independent oscillations.

    with angular velocities    


If you use this Applet frequently or if you are having ideas for further Applets, please send me an email. Thank you!  

Instructions
 

Tx =	period of oscillation parallel to x-axis
Ax =	amplitude of oscillation parallel to x-axis
Ty =	period of oscillation parallel to y-axis
Ay =	amplitude of oscillation parallel to y-axis
phi =	phase difference between the two oscillation (see formula^)


To change the parameters type the desired value into the appropriate box and confirm with ENTER. To leave permanent track marks, check the appropriate checkbox. To reset the applet to the initial conditions (the conditions after loading), click onto Reset.

Notes

• On slow systems a bug while trying to change the oscillator periods may occur.
• The graphics set used by the applet can be easily changed. Download for example the following file to change the look and unzip it into the directory where the .jar file is located:
