Like I said:
I started off by assuming an element of height dx at an elevation x above the ground. Then I assumed that the ray of light is incident at an angle of θ and that the angle of refraction isθ+dθ. the refractive index changes from μ(x+dx) to μ(x). So,
μ(x+dx)⋅sin(θ)=μ(x)⋅sin(θ+dθ)...

Question:[/B] Imagine you are in a massive desert. There is a tower of height H. A light source at the top of the tower can emit light in all directions. You are a person whose eyes are at a height h (h<H) above the ground. The refractive index of the air varies as μ=kd where...
