What type of relationship exists between the altitude and the atmospheric density, and what would the atmospheric density be at an altitude of 1,291 kilometers?

So this means an increase in either will decrease the other factor like density is mass per unit volume and it's also difficult to calculate with only altitude of 1,291 kilometers that's given.

Explanation:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
