In Young’s double slit experiment the wavelength of light was changed from . While doubling the separation between the slits which of the following is not true for this experiment
View answer and explanation
Correct option: D
The separation between successive dark fringes remains unchanged
Option D (The separation between successive dark fringes remains unchanged) is the correct answer because the fringe width is directly proportional to the wavelength and inversely proportional to the slit separation. Doubling the slit separation and halving the wavelength keeps the fringe width constant.
