Question

In the figure six lines of emission spectrum are shown. Which of them will be absent in the absorbtion spectrum.

• A. 1,2,3
• B. 1,4,6
• C. 4,5,6
• D. 1,2,3,4,5,6

Answer 1

The correct option is D 1,2,3,4,5,6

Here all electrons are coming from the higher state to lower state. So in the absorption spectrum there should be lower to higher state.
So, $1,2,3,4,5,6$ are the absent in the absorption spectrum.
