when a light ray enters a medium with refractive index n2 from a medium with refractive index n1 at curved surface with radius of curvature r is given by n2/v-n1/u=n2-n1/r now assume that the surface is plane and rewrite the formula with suitable changes

n2/v-n1/u=n2-n1/r

in case of plane surfaces radius of curvature [r] is infinity.

hence, n2-n1/r=0.

substitute this in equation , we get formula for plane surfaces, i.e

       n2/v-n1/u=0

   ==>n2/v=n1/u.
