In unielectron system, the wave number of any spectral line is directly proportional to

View answer and explanation

Correct option: C

\frac{1}{n_1^2}-\frac{1}{n_2^2}

Option C (

\frac{1}{n_1^2}-\frac{1}{n_2^2}

) is correct because the wave number is directly proportional to the difference in the inverse squares of the principal quantum numbers of the initial and final energy levels.
