A hydrogen atom has an ionization energy of 13.6eV. When it absorbs a photon with an energy

Question:

A hydrogen atom has an ionization energy of 13.6eV. When it absorbs a photon with an energy greater than this energy, the electron will be emitted with some kinetic energy.
(a) If the energy of such a photon is doubled, the kinetic energy of the emitted electron will (1) more than double, (2) remain the same, (3) exactly double, (4) increase, but less than double. Why?
(b) Photons associated with light of a frequency of 7.00 x 1015 Hz and 1.40 x 1016 Hz are absorbed by a hydrogen atom. What is the kinetic energy of the emitted electron?
