1. In a photoelectric experiment, the metal plate of an evacuated phototube is illuminated with monochromatic light of wavelength 365 nm. The current I in the circuit, is measured for various values of V, the applied potential difference between metal plate and collector. The results are shown in the below graph.

(i) Calculate the maximum kinetic energy of the photoelectrons.
(ii) Deduce the work function of the metal plate.

what is v/v and I/1*10^9 A in this graph.?

anonymous · Answer

that's one thing i got no idea about.... :/ i mean, the graph is V for x-axis and I for y-axis
