प्रश्न
Light of wavelength 2000 Å falls on a metal surface of work function 4.2 eV.
If the same light falls on another surface of work function 6.5 eV, what will be the energy of emitted electrons?

उत्तर
For this surface, electrons will not be emitted as the energy of incident light (6.2 eV) is less than the work function (6.5 eV) of the surface.
