Question

Which of the following transition in a hydrogen atom emits the photon of lowest frequency?

easy

Solution

Correct option is

n = 4 to n = 3

The energy levels get progressively closer as n increases. From the given sets, the closets to each other (hence, minimum energy difference levels) are n = 4 and n = 3.
