A.M. tends to hug the earth some and can bounce off the ionosphere. F.M. tends to go straight off into space thus it is hard to pickup at a distance.

What is the Wavelength range for FM?
The FM range is 88 - 108 MHz (with broadcast frequencies, or stations, assigned between 88.1 and 107.9 MHz every 0.2 MHz). The AM range is 535 - 1605 KHz (stations are assigned between 540 and 1600 KHz every 10 KHz).
Is microwaves are type of infrared wave?
Microwaves have a frequency range of about 300 MHz to about 300 GHz. Those frequencies are lower than infrared but higher than FM radio.No, they are usually considered separate ranges of the E.M. spectrum.
What wave has a shorter wavelength AM or FM?
Generally, the wavelength of an FM signal is shorter than an AM signal. A typical FM broadcast band is 88-108 MHz, while a typical AM broadcast band is 540-1660 KHz, making the FM signal wavelength 100 times shorter.
Why AM travels more faster than FM?
AM and FM are methods of delivering signals embedded in a carrier frequency. There are many applications for them but they are best known for radio applications AM means amplitude modulation. In this technique, the amplitude or height of the carrier signal increases and decreases as the base signal changes. AM radio signals will travel great distances so a single transmitter can cover large areas. FM means Frequency Modulation where the frequency of the carrier signal increases and decreases to represent the change in voltage of the base signal. FM signals tend to offer better signal quality than AM but the range is far less, demanding multiple transmitters to cover the same area as one AM transmitter.
AM radio waves are able to traves farther than FM radio waves because?
AM waves are reflected by earth's ionosphere
How far is the range on an FM tranmitter for a car radio?
The range on an FM transmitter for a car radio is roughly designed to transmit a radio signal to more than 500 meters away in the FM broadcasting band.
What is the transmitting range of 10kw FM transmitter?
As FM is transmitted using VHF, the transmitting range is more a matter of Line of Sight than transmitter power as these frequencies only follow straight lines.
How do you create transmitter?
we can create transmitter by using modulator circuit depending what frequency range you would like to use if you want to use FM range 88 to 108 MHz than you may refer to FM modulators and if you are going to more than 300MHz than you will need RF receiver.
Why FM is more clearer than am?
The abbreviations FM and AM stands for amplitude modulation and frequency modulation. The reason why FM is more clearer than AM is because FM has a better signal-to-noise ratio than AM does.
Why FM is good than am in communication?
The FM signal is more amune to static in the atmosphere than AM signals.
Why FM is used for voice signal?
Analog radio uses either amplitude modulation (AM) or frequency modulation (FM) to carry an audio signal. AM signals can be received at greater distances than FM but they suffer from interference from other stations and a wide range of electro-magnetic sources. FM signals offer better quality with less interference than is typically found with an AM signal. The transmission range is far smaller than AM. For a wide geographic coverage, multiple transmitters are needed although the limited range also makes FM an ideal medium for local stations where long range is undesirable.
What is the range of FM and Am broadcaster in km?
The range of FM and AM broadcaster in kilometres ranges from 6 to 70 kilometres.
What is FM frequency?
A: This term refers to the FM band or frequency range.
What are advantages of FM transmissions?
In FM, within small range of tuning, we can access multiple channel. We can access single channel in 0.5 MHz. Range of FM can go to several miles. FM needs comparatively less power.
Why is the area of coverage for AM radio greater than FM radio?
The basic reason is that AM radio is broadcast on a lower frequency, while FM is broadcast on a higher frequency. And the lower frequency signals will curve around the earth a bit more than the higher frequency FM signals. FM is considered more "line of sight" than AM, which has that "fat" ground wave that hugs the earth a bit more.
Is the frequency of radiation used in a microwave oven higher or lower than that of your favorite FM radio station broadcasting at 91.7x10 Hz?
Higher. Microwave ovens operate in the gigahertz range. Your FM station in the megahertz range is a hundred times less.
When was More FM created?
More FM was created in 1991.
