A diffraction pattern is obtained using a beam of red light. If red light is replaced by blue light then

Options

  1. Ano change in diffraction pattern.
  2. Bdiffraction bands become narrow and crowded together.
  3. Cdiffraction bands become broader and farther apart.
  4. Dbands disappear.

Correct answer

B. diffraction bands become narrow and crowded together.

Step-by-step solution

For diffraction, Distance between successive maxima is given aligned & by, = D a & _ blue _ red aligned The diffraction bands become narrow and crowded together.
