What is emission line spectrum?
(N/A) Each element emits radiation with different wavelengths depending on its temperature. Hence,each element has a characteristic spectrum of radiation which it emits.
When an atomic gas or vapour is excited at low pressure by passing an electric current through it,the emitted radiation has a spectrum which contains certain specific wavelengths only.
$A$ spectrum of this kind is known as an emission line spectrum.

When an electron in a hydrogen atom jumps to the innermost orbit,the radiation emitted belongs to which one of the following series?
If an electron in a hydrogen atom jumps from an orbit of level $n=3$ to an orbit of level $n=2$,the emitted radiation has a frequency ($R=$ Rydberg constant,$C=$ velocity of light).
For the wavelength of visible radiation of the hydrogen spectrum,Balmer gave an equation as $\lambda = \frac{(k m^2)}{(m^2 - 4)}$,where $m$ is an integer. The value of $k$ in terms of Rydberg's constant $R$ is
The ratio of minimum wavelengths of Lyman and Balmer series will be
The frequencies for the series limit of the Balmer and Paschen series are $f_1$ and $f_3$,respectively. If the frequency of the first line of the Balmer series is $f_2$,then the relation between $f_1, f_2$,and $f_3$ is:
