Answer:
n .= 1 to 4
Explanation:
From the Planck 5
E = hc/lambda
Where lambda is wavelength
E= hf
We will explain the answer here with respect to wavelength. It should be understood that the higher the wavelength of transition, the lower the frequency.
This means that longer transitions will occur at lesser frequencies. From the options the biggest transition is from 2 to 94, while the smallest is from 1 to 4
The transition from 1 to 4 is expected to have the highest energy as it has the shortest wavelength,
Transition from 2 to 94 has the longest wavelength, lowest energy and least frequency
