The graph shows that
(i)
the stopping potential V0 varies linearly with
the frequency of incident radiation for a given
photosensitive material (ii) there exists a certain minimum cut-off
frequency n0 for which the stopping potential
is zero Rationalised 2023-24

These observations have two implications:
(i)
The maximum kinetic energy of the photoelectrons varies linearly
with the frequency of incident radiation, but is independent of its
intensity (ii) For a frequency n of incident radiation, lower than the cut-off
frequency n0, no photoelectric emission is possible even if the
intensity is large
