Photo Electric Effect

Photo Electric Effect

1. Conclusions

   • 1. For a given material, no photoelectrons are emitted if the radiation has a frequency below a certain value, called the threshold frequency
   • 2. The photoelectrons are emitted with a variety of kinetic energies ranging from zero to some maximum value.
   • 3. The number of photoelectrons emitted per second is proportional to the instensity of the radiation.
