Which of the following expression represent the wave number of spectral lines in Balmer series (if

n

is the principal quantum number of higher energy level)?

View answer and explanation

Correct option: C

\frac{R(n-2)(n+2)}{4 n^2}

The correct answer is C. The wave number for the Balmer series is given by

\frac{R(n-2)(n+2)}{4 n^2}

, derived from the Rydberg formula.
