radio waves as reliable straight line
« on: March 14, 2019, 08:58:01 PM »
We know that light diffracts, that it does not travel straight through an edge between different materials and that P900s don't give exact RE or FE results because the light is bending.

Do radio waves have the same problem?

On FE, if I sight something through a telescope and a radar set, could it be in some other position than where it appears due to bending of both radio and light waves in the same way?

It absolutely can travel straight through without diffracting. Snell’s law demonstrates this!
