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.
