Question

WHAT IS ABSORPTION SPECTRUM ?

Answer 1

a spectrum of electromagnetic ration transmitted through a substance, showing dark lines or bands due to absorption at specific wavelengths.

Answer 2

Answer :

Absorption Spectrum -

• It is observed when the white light is passed through a solution or vapour.
• The solution or vapour is said to be of a chemical substance.
• The results obtained is a continuous spectrum with some dark bands in between.
• These dark bands are the result of absorption of light when it was passed through the chemical substance.
• According to the nature of the element, the light of certain wavelengths are absorbed.
• Further, the dark bands were found to be at the same place where coloured bands appeared when the light was emitted. (In emission spectra)
• This spectrum is discontinuous.
• The dark bands make it discontinuous or else it is a continuous spectrum.
