Understand that electron transitions involve electrons moving between energy levels in an atom. Absorption occurs when an electron moves from a lower energy level to a higher energy level.
Identify the initial and final energy levels for each transition given in the problem. For example, n = 5 to n = 3 means the electron starts at level 5 and moves to level 3.
Recognize that absorption requires the electron to move to a higher energy level, which means the final energy level (n) should be greater than the initial energy level.
Examine each transition: n = 5 to n = 3, n = 1 to n = 3, n = 6 to n = 2, and n = 7 to n = 4. Determine which transitions involve moving to a higher energy level.
Conclude that the transition n = 1 to n = 3 is an example of absorption, as the electron moves from a lower energy level (n = 1) to a higher energy level (n = 3).
