A hypothetical atom has four energy states as shown.
Which of the following transitions will produce the photon with the longest wavelength?
(A) n = 2 to n = 1
(B) n = 3 to n = 1
(C) n = 3 to n = 2
(D) n = 4 to n = 1
(E) n = 4 to n = 3
The correct option is: (E) n = 4 to n = 3
Explanation:
Big λ means the least energy based on E = hc/ λ. The least energy corresponds to the smallest energy level jump which is 4–3.
