Exp-1 To determine the refractive index of the material of prism using sodium light.
Exp-2 To determine the dispersion power of a prism.
Exp-3 To determine the resolving power of the prism.
Exp-4 To determine the wavelength of sodium light using a plane diffraction grating.
Exp-5 To determine the resolving power of a plane diffraction grating.
Exp-6 To verify Cauchy’s equation (Mercury light source required).
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.
