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

Options

  1. AThere shall be an interference pattern for red distinct from that for green.
  2. BThere shall be no interference fringes.
  3. CThere shall be alternate interference fringes of red and green.
  4. DThere shall be an interference pattern, where each fringe's pattern center is green and outer edges is red.

Correct answer

B. There shall be no interference fringes.

Step-by-step solution

Different colours will have different fringe width. Within a few fringes of red, there will be several fringes of violet.
Also, there will be overlapping of colours.
