QUESTION:

A light ray enters the atmosphere of the Earth and descends vertically to the surface a distance h 5 100 km 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 5 1.000 293 at the Earths surface. (a) Over what time interval does the light traverse this path? (b) By what percentage is the time interval larger than that required in the absence of the Earths atmosphere?
