Why does AM radio fade out when you are under a bridge but FM does not?
Answered by bobpursley
Primarily because of the wavelength. THE bridge shortens the available space for the long wave signal to travel thru, it is truncated. However, the FM wave, of much shorter wavelength, does not "notice" the bridge.
