medium

A photon collides with a stationary hydrogen atom in ground state inelastically. Energy of the colliding photon is $10.2 \ eV$. After a time interval of the order of micro second another photon collides with same hydrogen atom inelastically with an energy of $15 \ eV$. What will be observed by the detector

$2$ photon of energy $10.2\ eV$

$2$ photon of energy of $1.4\ eV$

One photon of energy $10.2 \ eV$ and an electron of energy $1.4\ eV$

One photon of energy $10.2\ eV$ and another photon of $1.4 \ eV$

(IIT-2005)

Solution

(c) Due to $10.2\ eV$ photon one photon of energy $10.2\ eV$ will be detected.
Due to $15\ eV$ photon the electron will come out of the atom with energy $(15 – 13.6) = 1.4\ eV.$
