Question

What is mean by absorption spectrum is photographic negative of emission spectrum

Answer 1

Answer:

when light passed through a sample it absorbs radiation of certain wavelength the missing wavelength which corresponds to the radiation absorbed by the matter leave dark spaces in bright continuos spectrum, it is called emission spectrum

Answer 2

Answer:

Explanation:

An absorption spectrum, unlike the emission spectrum, is like a photographic negative of the emission spectrum. For observing the absorption spectrum, electromagnetic radiations are bombarded on a sample which absorbs radiation of certain wavelengths. The wavelength of radiations absorbed by the matter contributes to the missing wavelength which leaves dark spaces in the bright continuous spectrum.
