Question

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

Select the correct option:

A

there shall be an interference pattern, where each fringe's pattern center is green and outer edges is red.

B

there shall be an interference pattern for red distinct from that for green.

C

there shall be no interference fringes.

D

there shall be alternate interference fringes of red and green.

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

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.
