A photon of energy10.2 eVcollides 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 of15 eV. What will be observed by the detector?

Options:

Answer:
A
Solution:

In the time of1μsfirst photon is emitted, due to second photon incident ionization of atom takes from ground state ( Like photo electric effect)
