A) The photon is absorbed and the electron moves to an intermediate energy level.
B) The photon is absorbed and the electron gets scattered
C) The photon is not absorbed. It gets scattered.
D) None of the above
Correct Answer: C
Solution :
Option (c) is correct. Explanation: When a photon hits an atom and the energy of the photon is equal to the gap between two electron energy levels of the atom, the electron in the lower energy level absorb the photon and jumps up to the higher energy level. If the photon energy does not correspond to the difference between two energy levels, then the photon will not be absorbed (it may be scattered away).
