Atoms And Nuclei Question 34

Question: 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). The following spectral lines will also occur in the absorption spectrum [CBSE PMT 1995]

Options:

A) 1, 4, 6

B) 4, 5, 6

C) 1, 2, 3

D) 1, 2, 3, 4, 5, 6

Show Answer

Answer:

Correct Answer: C

Solution:

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.
