1. There will be a central dark fringe surrounded by a few coloured fringes
2. There will be a central bright white fringe surrounded by a few coloured fringes
3. All bright fringes will be of equal width
4. Interference pattern will disappear

- interference pattern will disappear.
- there will be a central dark fringe surrounded by a few coloured fringes
- there will be a central bright white fringe surrounded by a few coloured fringes.
- all bright fringes will be of equal width
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
With white light, all wavelengths interfere. The central fringe is white due to constructive interference, while other fringes are coloured due to wavelength dependence.
