What is the minimum frequency of light required to eject an electron from a hydrogen atom in the ground state? Given that ionization energy (work function) of hydrogen atom is 13.6 eV. Calculate the kinetic energy and stopping potential of the ejected electron if the frequency of the incident light is twice the required frequency.
