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

A

`1, 2, 3`

B

`1, 4, 6`

C

`4, 5, 6`

D

`1, 2, 3, 4, 5, 6`

Text Solution

Verified by Experts

The correct Answer is:
A
The photon's with energies equal to that required for upward transition `A rarr X, A rarr B` and `A rarr C` would upward transition, these photon shell be absent from absorption spectrum.
