Accounting. Question 1) Calculate the shortest and longest wavelength in H- spectrum of Lyman series. \end{align*}} 29.3k SHARES. The shortest wavelength of H atom is the Lyman series is λ1. The longest wavelength is 656.3 nm; The second longest wavelength is 486.1 nm; And the third is 434.1 nm; Also, as the wavelength decreases the lines appear closer together and weak in intensity; He found a simple formula for the observed wavelengths: Further, for n=∞, you can get the limit of the series at a wavelength of 364.6 nm. In 1885, when Johann Balmer observed a spectral series in the visible spectrum of hydrogen, he made the following observations: The longest wavelength is 656.3 nm. Question 1) Calculate the shortest and longest wavelength in H- spectrum of Lyman series. The wavelength λ of the spectral line of Lyman series can be calculated using the following formula: $\frac{1}{\lambda} = R\left[ \frac{1}{1^2} - \frac{1}{n_2^2} \right]$ The longest wavelength is the first line of the series for which Finance. R H = 109678 cm-1? The frequency of light emitted at this wavelength is 2.47 × 10^15 hertz.
