The rays are travelling perp. to the plane having different optical media.
So the rays wont get deflected.

Since the rays enter at x = 1/B,
the U function becomes a function of z only.

u(z) = Az⁴+1

Total Optical path the ray traverses = ₀^câˆ«udz = Ac⁴4+c
Optical path introduced = Ac⁴4+c - c = Ac⁴4
