Solution: Consider the three electronic transitions in a hydrogen atom shown here, labeled A, B, and C.Calculate the wavelength of the photon emitted for transition A.

Problem

Consider the three electronic transitions in a hydrogen atom shown here, labeled A, B, and C.

A transition diagram shows that (A) is the large transition from n equals 2 to n equals 1; (B) is the medium transition from n equals 3 to n equals 2; and (C) is the small transition from n equals 4 to n equals 3.Graphs show three waves over the same distance with (i) very dense peaks and troughs, (ii) medium-density peaks and troughs, and (iii) very few peaks and troughs.

Calculate the wavelength of the photon emitted for transition A.
