Dear student,
Stopping potential for an incoming photon is equal to the energy of it per unit charge.
Hence stopping potential ofphoton is
Hence stopping potential of photon is Hence the required difference=0.34V

In 1st case : stopping potential=12400/4000=3.1ev. In 2nd case : stopping potential=12400/3600=3.44ev Difference=3.44- 2.06=0.34ev
