A photon collides with a stationary hydrogen atom in ground state inolestically . Energy of the order of inicro second another photon collicles with same hydrogen atom indastisically with an energy of 15 eV what will be observad by the detanctor?

A photon collides with a stationary hydrogen atom in ground state inelastically. Enorgy of the colliding photon is 10.2 eV. Almost instantaneously. Another photon collidos with same hydrogen atom inelastically with an energy of 15 eV. What will be observed by the detector ?

An electron of kinetic energy K collides elastically with a stationary hydrogen atom in the ground state. Then,

A neutron with a kinetic energy of 6.0 eV collides with a stationary hydrogen atom in its ground state. Explain why the collision must be elastic-that is, why kinetic energy must be conserved. (Hint: Show that the hydrogen atom cannot be excited as a result of the collision.)

An electron of kinetic enregy K collides elastically with a stationary hydrogen atom is the 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 ?
