The ratio of the wavelengths of the first Lyman line and the second Balmer line of hydrogen atom is
- A \(3: 4\)
- B \(1: 4\)
- C \(2: 3\)
- D \(1: 3\)
Answer & Solution
Correct Answer
(B) \(1: 4\)
Step-by-step Solution
Detailed explanation
\( \frac{1}{\lambda_L} = R \left( \frac{1}{1^2} - \frac{1}{2^2} \right) = R \frac{3}{4} \Rightarrow \lambda_L = \frac{4}{3R} \)…
