requally spaced c) Both equally & eneah
spored d) Forned by ta purified of war​

Answer 1

Explanation:

Fringe width =

d

λD

As the λ (wavelength), D (distance of screen from the slits) and, d (distance between the slits) remain the same, fringe width remains the same.

Hence all fringes are always equispaced.
