If the monochromatic source in Young’s double slit experiment is replaced by white light, then:
There will be a central bright white fringe surrounded by a few colored fringes.
All bright fringes will be of equal width.
Interference pattern will disappear.
There will be a central dark fringe surrounded by a few colored fringes.
To solve this problem, we need to understand the behavior of white light in Young's double slit experiment.• In Young's double slit experiment, when a monochromatic source is used, the interference pattern consists of alternating bright and dark fringes of equal width.• When the monochromatic source is replaced by white light, which contains multiple wavelengths, each wavelength will produce its own interference pattern.• The central fringe will be white because all wavelengths (colors) constructively interfere at the center.• Surrounding the central white fringe, there will be colored fringes. This is because different wavelengths (colors) will interfere constructively and destructively at different positions, creating a spectrum of colors.• The width of the fringes will vary for different colors because the fringe width is inversely proportional to the wavelength. Thus, red fringes will be wider than blue fringes.Therefore, the correct option is:Option 1: There will be a central bright white fringe surrounded by a few colored fringes.This explanation aligns with the behavior of white light in the double slit experiment.
