Dual Nature Of Radiation

The threshold frequency for a metal surface is '\(n_0\)'. A photo electric current '\(I\)' is produced when it is exposed to a light of frequency \(\left(\frac{11}{6}\right) \mathrm{n}_{\mathrm{o}}\) and intensity \(\mathrm{I}_{\mathrm{n}}\). If both the frequency and intensity are halved, the new photoelectric current '\(\mathrm{I}^1\)' will become:
