A monochromatic light source of frequency v incidents on a metallic surface and eject photoelectrons. The photoelectrons having the maximum energy are just able to ionize the hydrogen atoms in the ground state. The whole experiment is repeated again with an incident radiation of frequency (5v/6) , the photoelectron so emitted are able to excite the hydrogen atom beam which then emits a radiation of wavelength 1215 A. Determine the work function of the metal and the frequency v. (ionization potential of hydrogen atonm is 13.6 V)
