The diagram figure below shows a photocell connected in a circuit:-

(i) Complete the diagram by indicating the correct polarities in the gap for current to flow in
the circuit.
(ii) State and explain the effect of using light of different wave lengths on the amount of
current flowing in the circuit given that the distance of the source of light remains the same

Answers

ii) No change in the amount of photo current. Change in wavelength/frequency of the
radiation does not affect the amount of photo electrons produced. It is the number of
photo electrons that determines the photocurrent.
