NO
Yes!
microwave
They can be interfered by other transmission signals
Pfft. No. It uses Radio Signals. Not Radiation.. Radiation is from the Sun and Microwave Signals. :)
They get heated up, and get signals in them which make them unhealthy.
If it did you'd probably be dead
yes so is am fm radio and tv signals
Radio signals propagate faster than sound signals. Speed of light (radio) is about 186,000 mps Speed of sound is about 1100 fps (0.5 mps).
Buildings, hills, forests, and even heavy rain and snowfall all interfere with the transmission of microwave signals.
Reflection from the ionosphere.
Terrestrial TV signals will only propagate a finite distance. To see a TV signal from a distant place you need to have it broadcast via a satellite in orbit round the Earth.
