A light ray enters the atmosphere of a planet and descends vertically to the surface a distance h below. The index of refraction where the light enters the atmosphere is 1.00, and it increases linearly with distance to have the value n at the planet surface.

 

(a) Over what time interval does the light traverse this path? (Use any variable or symbol stated above along with the following as necessary: c.)
Δt =

(b) By what fraction is the time interval larger than that required in the absence of an atmosphere (t0)? (Use any variable or symbol stated above along with the following as necessary: c.)
Δt
t0
=
