When light is incident on a diffraction grating, the zero order principal maximum will be

Options

  1. Aone of the component colours
  2. Babsent
  3. Cspectrum of the colours
  4. Dwhite

Correct answer

D. white

Step-by-step solution

Zero order principal maximum contains all incoming wavelets in diffraction pattern, Hence, zero order principal maximum will be white.
