Question

In FIGURE Q$41.12,$a photon with energy $2.0eV$is incident on an atom in the $p$state. Does the atom undergo an absorption transition, a stimulated emission transition, or neither? Explain.

Short answer

The given statement is proved.

Step-by-step solution

Given Information 

We have to given a photon with energy$2.0eV$.

Simplify

Here, shows an energy difference between the $p‐$state and the lower $s‐$state. Know that the energy of a photon matches the energy difference between the $p‐$state and the lower $s‐$state. The atom may a stimulated emission transition, but it will not undergo an absorption transition.
