We’re being asked to determine which transition results in the emission of light with the shortest wavelength. Recall that starting from n = 1, the distance between each energy level gets smaller as shown below:
Emission is a transition process from a higher energy level to a lower energy level. This rules out choices B and C. Recall that the energy of a photon is given by:
We can see that energy and frequency are directly proportional. The energy in a transition also depends on the distance between the energy levels.
Which electronic transition in the hydrogen atom results in the emission of light of the shortest wavelength?
A. n = 4 to n = 3
B. n = 1 to n = 2
C. n = 1 to n = 6
D. n = 3 to n = 1
E. n = 2 to n = 1
