JEE Mains · Physics · STD 12 - 10. Wave optics
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...
- A There shall be an interference pattern for red distinct from that for green.
- B There shall be no interference fringes.
- C There shall be alternate interference fringes of red and green.
- D There shall be an interference pattern, where each fringe's pattern center is green and outer edges is red.
Answer & Solution
Correct Answer
(B) There shall be no interference fringes.
Step-by-step Solution
Detailed explanation
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.
