Which of the following quantum leaps would be associated with the greatest energy of emitted light?
n= 2 to n= 5
n= 5 to n= 1
n= 5 to n= 4
n= 4 to n= 5

Quantum leaps n = 5 to n = 1 would be associated with the greatest energy of emitted light.

Option B

Explanation:

As per the hydrogen series, the wave number is inversely proportionate to the transition number of energy levels. So the increase in the difference between transition levels will lead to increase in the wave number. And wave number is directly proportional to the energy of the emitted light.

Thus, among the spectral series of hydrogen atom, Lymann series has the largest energy of the emitted light. So among the given options, n = 5 to n= 1 is the quantum leaps which would lead to greatest energy of the emitted light.
