In Young's double slit experiment, the distance between two coherent sources is 1 mm and the distance between the slits and the screen is 1 m. If the 10th dark fringe is at a distance of 4.75 mm from the central bright fringe, calculate
the distance of 5th bright fringe from the central bright fringe.

Explanation

For fifth bright fringe, n = 5, Distance from central fringe, `x_n=n beta`
Result : Wavelength of the light = 500 nm and the distance of the `5^(th)` bright fringe from the central bright fringe = 2.5 mm
