The second line of Balmer series has wavelength \(4861 Å\). The wavelength of the first line of Balmer series is
- A \(1216 Å\)
- B \(6563 Å\)
- C \(4340 Å\)
- D \(4101 Å\)
Answer & Solution
Correct Answer
(B) \(6563 Å\)
Step-by-step Solution
Detailed explanation
Wavelength of the second line of Balmer series, \(\lambda_2=4861 Å\) \(\frac{1}{\lambda_2}=R\left(\frac{1}{2^2}-\frac{1}{n^2}\right)\) For second line, \(n=4\)…
