Photoelectric Effect

    What is the relationship between the maximum electric current and the intensity of incident light?
    -are the inversely proportional?


    What colour has the larges cutoff potential?
    -is it yellow?

    Is cutoff potential effected for violet light?
    -no???


    How do you calulate maximum kinetic energy of ejected electrons using wavelength?

    Photoelectric equation is

    [tex]eV_0=\frac{hc}{\lambda}-\phi[/tex]

    where V0 is cuttoff potential and phi is the work function of the metal
