Question
Characteristic X-ray are produced due to
Options
A.transfer of momentum in collision of electrons with target atoms
B.transition of electrons from higher to lower electronic orbits of an atom
C.heating of the target
D.transfer of energy in collision of electrons with atomus in the target.
Solution
When we bombard electrons on a target consisting of heavier atoms, the electron ofinner orbitals of target atoms get knocked out. So to fill their position, other electrons from the higher energy orbitals make transition to lower energy orbitals. Its results is emission of X-rays.
