MP Board · Class 12 · Physics · Wave OpticsIn Young's double slit experiment, the fringe width (beta) is given by the formula:
Step-by-Step Solution
The correct answer is beta = lambda D / d. Here, lambda is the wavelength of light, D is the distance between the slits and the screen, and d is the distance between the two slits.
