What is the ratio of the wavelength of the Lyman series limit to that of the Paschen series limit in the hydrogen spectrum?
What is the ratio of the wavelength of the Lyman series limit to that of the Paschen series limit in the hydrogen spectrum?
The first member of the Paschen series in the hydrogen spectrum is of wavelength \( 18800 \, \text{Å} \). What is the short wavelength limit of the Paschen series?
The wave number of the last line of the Balmer series in the hydrogen spectrum will be ($R = 10^7\text{ m}^{-1}$)
\(\lambda_1\) is the wavelength of series limit of Lyman series, \(\lambda_2\) is the wavelength of the first line of Lyman series and \(\lambda_3\) is the series limit of the Balmer series. Then the relation between \(\lambda_1\), \(\lambda_2\) and \(\lambda_3\) is
