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 ?
