Work function of metal X is equal to `3.5 eV` and work function of material Y is equal to ionization energy of He+ ion in its first excited state. Light of same wavelength is incident on both X and Y. The maximum kinetic energy of photoelectrons emitted from X is twice that of photoelec- trons emitted from Y. Find the wavelength of incident light. `hc = 12400 eV Å`.
