We looked at the photoelectric effect this week.  There is a useful simulation of the photoelectric effect here.  You can change the metal under investigation to confirm that different metals have different work function values.  You can also vary the wavelength and irradiance of the light.

Notice that below the theshold frequency you can’t get any photoelectrons, even if you set the light to its brightest setting.
