We’re being asked to determine which energy gap gives the longest wavelength. Recall that starting from n = 1, the distance between each energy level gets smaller as shown below:
Consider the following portion of the energy-level diagram for hydrogen:
n = 4 –0.1361 × 10 –18 J
n = 3 –0.2420 × 10 –18 J
n = 2 –0.5445 × 10 –18 J
n = 1 –2.178 × 10 –18 J
For which of the following transitions does the light emitted have the longest wavelength?
A. n = 4 to n = 1
B. n = 4 to n = 2
C. n = 4 to n = 3
D. n = 3 to n = 2
E. n = 2 to n = 1
