## Homework Statement

I don't know if 'hops' is the correct English term, but that's the term my assignment uses in Dutch. The assignment is about the reflection of radiowaves by the f1-layer in the atmosphere and a hop is defined as one such reflection. The question is, what is the minimum amount of hops needed for a radiowave to travel from Amsterdam to Tokyo? We have to use Mathematica to solve it.

## Homework Equations

First of all we have to calculate the spherical distance from Amsterdam to Tokyo. I calculated this to be 9293.71 km. Then we have to calculate the angle between Amsterdam and Tokyo, as seen from the centre of the earth, in radians, which I found to be 2.3541.

## The Attempt at a Solution

I'm pretty much at a loss now, how do I continue?
