Question

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

• A. Two photons of energy 10.2 eV
• B. Two photons of energy 1.4 eV
• C. One photon of energy 10.2 eV and one electron of energy 1.4 eV.
• D. One electron having kinetic energy nearly 11.6 eV

Answer 1

The correct option is D One electron having kinetic energy nearly 11.6 eV

One electron having kinetic energy nearly 11.6 eV
