The maximum kinetic energy and the stopping potential are Kmax and V0, respectively. If the frequency incident on the surface is doubled, both the Kmax and V0 are also doubled. Statement II The maximum kinetic energy and the stopping potential o photo-electrons emitted from a surface are linearly dependent on the frequency of incident light.

an electron of energy 5.6 eV passes through mercury vapour and emerges with an energy 0.7 eV. The minimum wavelength of photons emitted by mercury atoms is close to In a Frank-Hertz experiment respectively. If the frequency incident on the surface is doubled Statement I A metallic surface is irradiated by a monochromatic light of frequency v > v0 (the threshold frequency). The maximum kinetic energy and the stopping potential are Kmax and V0
