Waves ...

[iamamn]

1. The problem statement, all variables and given/known data

It is possible for radio waves to be transmitted over long distances even though the curve of the earth blocks a direct path for the radio waves to travel (e.g. in Scotland it is possible to pick up broadcast from many distant foreign countries.)




The attempt at a solution

In class we have only studied DIFFRACTION.
bending of waves round short corners; long waves diffract more than short waves.


I was just wandering if that was the right answer?

Thanks,
