Saturation current is the maximum current possible and it will be directly proportional to the number of number of electrons falling on collector plate per second which depend on number of photons
incident on the cathode as one photon contribute in one electron and the number of photons is actually
proportional to intensity which varies
As intensity I∝1/r2, where r is the distance
So the correct graph will be decreasing with power2 of distance and it will be rapidly decreasing with a higher value of r.
incident on the cathode as one photon contribute in one electron and the number of photons is actually
proportional to intensity which varies
As intensity I∝1/r2, where r is the distance
So the correct graph will be decreasing with power2 of distance and it will be rapidly decreasing with a higher value of r.
