Spectrum

What Is Spectrum?


       A spectrum is an array of waves or particles which is spread out according to the increasing or decreasing of some property such as wavelength or frequency.

Types of Spectrum


      Depending on the nature of the source emitting the radiation, there are two types of spectra.
  1. Emission Spectra
  2. Absorption Spectra
Emission spectra are further two types:-
  • Continuous spectrum
  • Discontinuous spectrum which may be a band spectrum or line spectrum. Line spectrum also called atomic spectrum.
