    Phya5 photoelectricty
    A few questions:
    1. How did classical wave theory fail to explain photelectric effect?
    2. What is stopping potential?
    3. How is stopping potential measured using potential divider and vacuum photocell?
    4. Why do the photoelectrons have a range of kinetic energies?
    5. Why was Einstein's explanation of photoelectricity significant in terms of EM radioation?


    Thanks
