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

Options

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

Answer

C
