Which atomic spectra are continuous and which are discontinuous in the following: 1) Emission Spectra 2) Absorption Spectra?

Content Curator

Atomic spectra are the spectrum of electromagnetic radiations emitted or absorbed by electrons during the transition between different energy levels.

Atomic Spectra are classified into two types:

Emission Spectra
Absorption spectra

Emission Spectra: The electrons in atoms or molecules absorb energy and lose their stability when transit to high energy levels from low energy levels whenever white light or electromagnetic radiation interacts with them.

The electrons will emit energy in the form of radiation in order to regain their stability.
The radiation emitted will constitute a spectrum of distinct wavelengths known as Emission spectra.
It is also known as a line emission spectra because the spectrum obtained is distinct and discontinuous.

Absorption spectra: Whenever electromagnetic radiation interacts with atoms, The electrons of the atom at the ground level jump to a higher energy level, absorbing energy will result in a continuous spectrum with dark lines, which is known as an absorption spectrum.
