Detailed explanation-1: -How is this possible? Since AM radio operates at a lower frequency, it has much larger wavelengths. Larger wavelength waves can travel farther because they can travel well through solid objects. FM radio waves on the other hand do not travel well through solid objects.
Detailed explanation-2: -Radio-wave communications signals travel through the air in a straight line, reflect off of clouds or layers of the ionosphere, or are relayed by satellites in space.
Detailed explanation-3: -The FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7.
Detailed explanation-4: -Electromagnetic radiation travels in waves that “vibrate” at different frequencies. Radio waves are in the range of about 10 kHz (or ten thousand waves per second) to 100 GHz (which is one hundred million vibrations per second).
