Question

Among the following h atom transitions, which would emit a photon of light with the greatest energy?

a. n=5 to n=2
b. n=4 to n=2
c. n=2 to n=1
d. n=5 to n=4
e. n=6 to n=3

Answer 1

d

Step-by-step explanation:

Energy is inverse to wavelength. You can see the relationship from the combined formula E=hc/λ that if wavelength increases, energy will decrease and vice versa.

From this image you can see the electron transition series, which shows the length between energy levels. The shortest length corresponds to the highest energy transition. The shortest will be between n=5 and n=4.
