If the Young's double slit experiment is performed with white ligh...
(a) The central fringe will be white.
(b) There will not be a completely dark fringe.
(d) The fringe next to the central will be violet.
EXPLANATION:
The central fringe will be white because all the component colors band will superimpose here. The option (a) is true.
Since the fringes of different wavelengths of light have different fringe-widths, there will not be a completely dark fringe. Option (b) is true.
Since the wavelength of the violet light is nearly half of the red light, the fringe-width of the violet light is half of the red light. Since the central bright violet fringe combines with other fringes to form the white fringe, the next to it will be a minima for violet light. So violet will not be next to the central white fringe. Next will be a very thin band of white light minus violet light which will give a shade of off white. In this way, the components of indigo, blue, green, yellow and orange colors will be withdrawn respectively in the very thin consecutive bands. These will effect in different off white shades which cannot be clearly differentiated from the white band. The first color away from the center will be recognized as red when in these very thin bands yellow+orange+red, orange+red or red remains. hence the option (c) is true.

Young's Double Slit Experiment with White Light
Introduction:
Young's double-slit experiment is a classic experiment in optics that demonstrates the wave nature of light. In this experiment, light is passed through two tiny slits and then allowed to interfere. The interference produces a pattern of bright and dark fringes that can be observed on a screen.
White Light in Young's Double Slit Experiment:
When white light is used in the experiment, it consists of a mixture of different colors. Each color has a different wavelength and hence different colors of light will diffract at different angles at the diffraction grating. As a result, the bright and dark fringes will be colored.
Options and Explanation:
a) The central maximum will be white: This statement is true as the central maximum will be formed by the superposition of all the colors of light, resulting in white light.
b) There will not be a completely dark fringe: This statement is also true as there will always be some amount of light passing through both the slits, resulting in a minimum intensity rather than complete darkness.
c) The fringe next to the central will be red: This statement is false. The fringe next to the central maximum will be violet as it is formed by the diffraction of light with the shortest wavelength.
d) The fringe next to the central will be violet: This statement is true as explained in the previous point.
Conclusion:
Thus, option c) is the correct answer as the fringe next to the central maximum will be violet and not red. This is because the diffraction of light depends on the wavelength of light and not on its color.
