Question

In hydrogen atom spectrum, ( $R \rightarrow$ Rydberg's constant)

A. the maximum wavelength of the radiation of Lyman series is $\frac{4}{3R}$

B. the Balmer series lies in the visible region of the spectrum

C. the minimum wavelength of the radiation of Paschen series is $\frac{9}{R}$

D. the minimum wavelength of Lyman series is $\frac{5}{4R}$

Choose the correct answer from the options given below:

Accepted Answer

$\frac{1}{\lambda} = R\left( 1 - \frac{1}{4} ight)$$$\lambda = \frac{4}{3R}$$$$\begin{matrix} & \frac{1}{\lambda'} = R\left( \frac{1}{9} ight) \ & \lambda' = \frac{9}{R} \end{matrix}$$
