Q. The figure indicates the energy level diagram of an atom and the origin of six spectral lines in emission ($e.g.$ line no. 5 arises from the transition from level $B$ to $A$). Which of the following spectral lines will also occur in the absorption spectra
A) 1, 4, 6
B) 4, 5, 6
C) 1, 2, 3
D) 1, 2, 3, 4, 5, 6
Explanation
(c) The absorption lines are obtained when the electron jumps from ground state $(n = 1)$ to the higher energy states. Thus only 1, 2 and 3 lines will be obtained
