Answer & Solution
Correct Answer
(D) (D), (C), (A), (B)
Step-by-step Solution
Detailed explanation
Frequency \( \nu \propto \frac{1}{n_1^2} - \frac{1}{n_2^2} \). Lyman series: \( n_1 = 1 \) (Highest frequencies) Balmer series: \( n_1 = 2 \) Paschen series: \( n_1 = 3 \) Bracket series: \( n_1 = 4 \) (Lowest frequencies) Ascending order of frequencies: Bracket Order of given…
