The ratio of longest wavelengths of the spectral lines in the Lyman and Balmer series of hydrogen spectrum is
- A \(\frac{3}{23}\)
- B \(\frac{5}{27}\)
- C \(\frac{7}{29}\)
- D \(\frac{9}{31}\)
Answer & Solution
Correct Answer
(C) \(\frac{7}{29}\)
Step-by-step Solution
Detailed explanation
The longest wavelength for Lyman series \((2 \rightarrow 1)\) \(\frac{1}{\lambda_{\mathrm{L}}}=\mathrm{R}\left(\frac{1}{(1)^2}-\frac{1}{(2)^2}\right)=\frac{3}{4} \mathrm{R}\) And for Balmer series \((3 \rightarrow 2)\)…
