Question

If radiation of all wavelengths from ultraviolet to infrared is passed through hydrogen gas at room temperature absorption lines will be observed in the

• A. Lyman series
• B. Balmer's series
• C. Both (1) and (2)
• D. Neither (1) or (2)

Answer 1

The correct option is A Lyman series

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