Question

For Balmer series in the spectrum of atomic hydrogen, the wave number of each line is given by $\overset{-}{v} = R_H (\frac{1}{n_1^2} - \frac{1}{n_2^2})$ where $R_H$ is a constant and n₁ and n₂ are integers. Which of the following statement(s) is (are) correct?
I. As wavelength decreases, the lines in the series converge.
II. The integer n₁ is equal to 2.
III. The ionization energy of hydrogen can be calculated from the wave number of these lines.
IV. The line of longest wavelength corresponds to n₂ = 3.
(a) I, II and III
(b) II, III and IV only
(c) I, II and IV
(d) II and IV only
