Problem

A man of height 2m is standing on level road where because of temperature variation the refractive index of air is varying is

\mu = \sqrt{1 + ay}

, where y is height from road. If

a = 2 \times 10^{-6} \,\text{m}^{-1}

Then find the maximum distance, in km, till which he can see on the road
