In a Young's double slit experiment, the source is white light. One of the holes is covered by a red filter and another by a blue filter. In this case

Options

  1. Athere shall be alternative interference fringes of red and blue.
  2. Bthere shall be interference fringes for red distinct from that for blue.
  3. Cthere shall be no interference fringes.
  4. Dthere shall be interference fringes for red mixing with one for blue.

Correct answer

C. there shall be no interference fringes.

Step-by-step solution

Both the blue and red light have different wavelengths and for interference fringes to be seen, we require coherent light sources.
