A photon collides with a stationary hydrogen atom in ground state inelastically. Energy of the colliding photon is 10.2 eV. After a time interval of the order of micro second another photon  collides with  same hydrogen  atom inelastically with an energy of 15eV. What wil be observed by the detector?    (a) 2 photons of energy 10.2 eV    (b) 2 photons of energy 1.4 eV    (c ) One photon of energy 10.2 eV and an electron of energy  1.4 eV   (d) One photon of energy 10.2 eV and another  photon of energy 1.4 eV
