For performing the simulation:

1. Select the material for studying photoelectric effect.

2. Select area of the material,wave-length,intensity of incident light.

3. Switch on the light source.

4. Measure the reverse current for various reverse voltages.

5. Plot the current-voltage graph and determine the threshold voltage.

6. Repeat the experiment by varying the intensity for a particular wavelength of incident light.

7. Repeat the experiment  by varying the wavelength for a particular intensity of  the incident light .
