Solution

Solution Steps

Step 1: Identifying the ground state

The ground state is the lowest energy level. In the given diagram, A is the lowest energy level.

Step 2: Determining the number of excited states

Excited states are energy levels above the ground state. B and C are above A. Therefore, there are two excited states.

Step 3: Finding the number of absorption lines

Absorption lines correspond to transitions from a lower energy level to a higher energy level. Possible transitions are A to B, A to C, and B to C. Thus, there are three possible absorption lines.
