The shape of the

Answer :

In Young’s double slit experiment, all fringes are of equal width. Fringe width is given by

Where, is fringe width, is wavelength, D is distance between slit and screen and d is the distance between two slits.

If D

Since, where n= 1,2,3…..

Where, x is the position of point observed from central maxima. Therefore, the shape of the interference fringes will be hyperbolic.
