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
