  • Refractive Index.
  • Resolving power.
  • Dispersion.
  • Prism.
  • Diffraction grating.

Principle and Working :

The working of a spectrometer is based on the principle that when light falls on an optical device such as a prism or diffraction grating each wavelength is refracted or bent by a unique angle. A precise spectrum can be determined by measuring the angles at which light is refracted or bent.
