Physics Applets

Cathode Ray Tube

Link: Simulation


This applet traces the path of an electron through the steering plates of a cathode ray tube. The path of the electron and the image on the display are both shown. The final deflection of the electron from the axis is calculated and given.

Scrollbars allow control over:

The mouse can also be used to change the length and separation of the deflection plate and the position of the screen.
