A photon of `10.2 eV`. Energy collides with a hydrogen atom in ground state inelastically. After few microseconds one more photon of energy `15 e V` collides with the same hydrogen atom. Then what can be detected by a suitable detector.

A photon of energy 10.5eV is allowed to interact with a hydrogen atom in its ground state. Then :

A photon of energy 10.2eV collides inelastically with a stationary hydrogen atom in the ground state. After a time interval of the order of a microsecond, another photon collides with energy of 15eV. What will be observed by the detector ?
