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.

What is the motto of Preston FM?
The motto of Preston FM is 'Your Community, Your Radio'.
Can you convert an am radio into FM?
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.
No FM radio on 2000 windstar my FM radio will not receive a siginal but am will is it thr radio or antanna?
Two things to check. Did it lose the ground and is the antenna disconnected?
What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
What is an Integrated FM modulator?
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.
What are the differences between AM and FM waves?
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.
What are the differences between AM and FM radio?
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.
Difference between satellite radio and regular radio?
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.
What are FM waves?
FM waves, or frequency modulation waves, are a type of electromagnetic wave used in radio broadcasting. They carry audio information by varying the frequency of the wave, resulting in clearer sound quality and less susceptibility to interference compared to AM waves. FM radio stations are assigned specific frequencies to prevent signal overlap.
Which waves carries AM and FM signals?
Radio waves
Which has a higher frequencies am radio waves or fm 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
What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
What transverse wave may be AM or FM?
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.
What is the use of radio waves?
hearing FM and am news in radio
Why do am radio waves diffract more than FM radio waves?
AM radio waves have longer wavelengths compared to FM radio waves. This means that AM waves are better able to diffract around obstacles and travel farther distances. FM radio waves, with their shorter wavelengths, are less prone to diffraction and tend to travel in straight lines, making them more susceptible to obstacles blocking their path.
AM radio waves are able to traves farther than FM radio waves because?
AM radio waves have longer wavelengths compared to FM radio waves, allowing them to diffract or bend around obstacles such as buildings and hills. This enables AM radio waves to travel greater distances and provide better coverage in areas with obstructions. FM radio waves, on the other hand, travel in straight lines and are more affected by obstacles.
Is determined by the medium wave?
The determination of the medium wave frequency range is between AM and FM radio frequencies. Medium waves have lower frequencies than FM but higher frequencies than long waves. They are commonly used for AM radio broadcasting.
