AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal.
FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.
In AM the amplitude of the carrier signal is modulated according to the amplitude of the signal to transmitted but in FM the frequency of the carrier is changed without any change in amplitude of the carrier.
AM stands for amplitude modulation, and FM stands for frequency modulation. As a wave, they are essentially the same, but they differ in the way that a radio receives them. For an AM radio, the sound is played based on the amplitude of the wave, while with FM radios, the wave is read for slight changes in frequency. These changes are what create the sound that is played.

The motto of Preston FM is 'Your Community, Your Radio'.
Yes, you can. You need to make an FM receiver and attach it to the receiver coil. You'll need to install a switch so you can switch between them, as well.
Two things to check. Did it lose the ground and is the antenna disconnected?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
A device that will allow you to send a FM signal. Usually used for mp3 or satelite radio players. You can set the modulator to a channel then your radio to the same channel and pick up the signal.
FM radio uses frequency modulation to broadcast sound over radio. FM radio waves are usually transmitted between 87.5 to 108.0 megahertz.
There is no fundamental difference in the waves. It so happens that in the USA, commercial AM radio broadcasts in a frequency band around 1 MHz, and FM radio broadcasts in a band around 100 MHz, so their frequencies and wavelengths are different. But that has nothing to do with being AM or FM waves. The codes used to manipulate the waves in order to make them carry information are different for AM and FM, but there's no physical difference in the waves themselves.
The main difference between AM and FM radio is the dial-in number and the amount of static each receive. AM radio preceded FM radio, with FM becoming popular in the 1950s.
One of the main differences between satellite radio and FM radio is that there is a cost for satellite and FM is free. Satellite radio also does not operate using the same numerical AM and FM channels as FM radio.
Radio waves
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
AM and FM are modulation types, that can probably be used for different kind of waves; but they are usually applied to radio waves. Radio waves are a kind of electromagnetic waves.
hearing FM and am news in radio
AM waves are reflected by earth's ionosphere
FM waves are of higher frequency than am waves.AM radio ranges from 535 to 1705 kilohertzFM radio ranges in a higher spectrum from 88 to 108 megahertz.
FM radio works like light. If a shadow is made (something in the way) , you get less light. Radio waves work in a straight line. If something is in the way, less radio waves. The rule is broken here if you use Am radio waves. Low clouds can make the waves bounce between the clouds and the ground and can travel as far as 1000 miles or further. So the answer is yes.
