A) 2 photon of energy 10.2 eV
B) 2 photon of energy 1.4 eV
C) One photon of energy 10.2 eV and an electron of energy 1.4 eV
D) One photon of energy 10.2 eV and another photon of 1.4 eV
Correct Answer: C
Solution :
[c] \[13.6\,\,eV\] energy needed to liberate the electron form hydrogen atom. So electron will liberate with kinetic energy\[=15-13.6=1.4\,\,eV.\]You need to login to perform this action.
