  • The diffraction grating is often used in the laboratories for the determination of wavelength of light.
  • The grating spectrum of a given source of monochromatic light is obtained by using spectrometer. The arrangement is as shown above.
  • The spectrometer is first adjusted for parallel rays. The grating is then placed …
