Ultraviolet light is used for a photo-electric effect experiment on cadmium. For a given photon wavelength, the energy of the most-energetic emitted electrons is measured to be 8 eV. The experimenter doubles the wavelength of the ultraviolet light and measures a different electron energy:
2 eV |
||
4 eV |
||
8 eV |
||
16 eV |
||
32 eV |
In this question we have to determine the maximum kinetic energy of ejected electrons when wavelength of incident light is doubled.
