If radiation of allow wavelengths from ultraviolet to infrared is passed through hydrogen agas at room temperature, absorption lines will be observed in the :

Lyman series

Balmer series

both $(A)$ and $(B)$

neither $(A)$ nor $(B)$

Solution

For hydrogen atom only one electron is present at ground state. when it absorb energy of different wavelength, it transist from $n =1$ to $n =2,3,4$ and so on, so, only lymen series id obsererved due to absence of electron on other energy level.

(IIT-2003)

Hydrogen $(H)$, deuterium $(D)$, singly ionized helium $(He^+)$ and doubly ionized lithium $(Li^{++})$ all have one electron around the nucleus. Consider $n = 2$ to $n = 1$ transition. The wavelengths of emitted radiations are $\lambda_1, \lambda_2 \lambda_3$ and $\lambda_4$ respectively.
