Answer to Question #143739 in Molecular Physics | Thermodynamics for Viccy

Question

Distinguish between emission and absorption spectra

Answer 1

Absorption spectra are where light of specific wavelengths has been absorbed by the atom these are seen as dip in the spectrum.

And absorption spectra occurs when an electron jumps from lower to higher orbital by absorbing energy.

where as emission spectra are the electromagnetic lines when atom releasing photons at specific wavelengths.

And emmission spectra occurs when an electron jumps from higher orbital to lower orbital by releasing energy as electromagnetic radiation.
