Microwave towers are normally set up in "Line of sight" pattern, as long as the other tower can be clearly seen from the antenna height (both), they work very well. On average they're set roughly about 30 to 40 miles apart depend upon terrain. The old AT&T towers "long line" towers were for sure.
diffraction
They can be any distance apart depending on the focal length and magnification.
because the molecules are so far apart.
no but the particles in a solid vibrate
I
Not as far apart as stars are from each other, but yes, they are a long way apart.
They are 90 feet apart.
The bonds that hold water molecules far apart from each other are ice. The hydrogen bonds' postulation in ice keeps them far apart from one another.

90ft
100 yards apart from each other
Microwave is a "line of sight" system, so the two points must be able to "see" each other. If they're linked by satilite, that can be around the world, and if by microwave towers then as far as you can see the tower.
There were the length of the ship apart.
Fire extinguishers shall be mounted 75 feet apart
Not as far as i know.
a days worth of traveling
Far apart.
