Dual Nature of Radiation

same energy Photoelectric current is zero when the stopping potential is
sufficient to repel even the most energetic photoelectrons, with the
maximum kinetic energy (Kmax), so that
Kmax = e V0
(11 1)
We can now repeat this experiment with incident radiation of the same
frequency but of higher intensity I2 and I3 (I3 > I2 > I1) We note that the
saturation currents are now found to be at higher values
