The explanation of photoelectric effect using both Wave and particle properties of light opened up a new realm of physiscs. Explore the photoelectrc effect with this progam and how it helped change the face of physics

Explore the effect by:

  • Adjusting the intensity of the light.
  • Adjusting the wavelength of the light.
  • Change the metal/Work function used.
  • Vary the retarding potential.
  • Determine the cut off voltage for given metals

The Virtual photoelectric effect program is $20 (U.S.). The program can be used at home by the students enrolled at the school the software is liscensed to.

For a single school
To order the program for your school and receive the registration codes and individual program immediately upon registration, click Here.

For a district/board or multiple schools
If you would like to buy a license for multiple schools contact "info (at)". The program(s) of your choice can be configured into a single file and include your district/board logo for easy use at all the schools you register for. No registration codes will be required to run the file.
