There are no such things as 'AM' and 'FM' waves.
When we take an electromagnetic wave, and force it to carry information by changing
its amplitude according to some pattern related to the information, we operate on it
with the process of 'AM'. Commercial radio stations that add sound information to
their carrier waves in that way operate in the frequency band of 0.55 - 1.7 MHz
(in the US).

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.
What part of the electromagnetic spectrum usually used for communication is?
The radio wave part of the electromagnetic spectrum is typically used for communication because it can travel long distances and pass through obstacles like buildings or clouds. Radio waves have varying frequencies, which are used for different types of communication such as AM/FM radio, television, cell phones, and Wi-Fi.
What are the two types of waves in radio waves and gamma rays?
The two types of waves in radio waves are AM (amplitude modulation) and FM (frequency modulation). In gamma rays, there are no different types of waves as they are all high-energy electromagnetic waves.
Is a infrared wave a form of an electromagnetic radiation?
For a long time, scientists thought that gravity might be an extremely long waved form of electromagnetic energy. Since then, scientists found that all forms of electromagnetic energy travel in little bundles called photons and they have established that these photons have mass and they have also established that gravity has no mass so it is not a form of electromagnetic energy.
Which station's signal has waves with longer wavelengths?
electromagnetic waves with a longer wavelength has
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 has a greater frequency am waves or FM waves?
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.
Is air an example of an electromagnetic wave?
No. -- A fruitcake is a mixture of solids. It is not an electromagnetic wave. -- A martini is a mixture of liquids. It is not an electromagnetic wave. -- Air is a mixture of gases. It is not an electromagnetic wave. -- White light is a mixture of electromagnetic waves. -- An FM radio signal is a mixture of electromagnetic waves.
When was Spectrum FM created?
Spectrum FM was created in 1996.
What are electromagnetic spectrum waves?
They go by many names in everyday life. Here are a few of them: -- AM -- FM -- TV -- GPS -- cellphone signal -- wireless -- microwave -- heat -- red light -- green light -- blue light -- tanning rays -- X-rays

When was Waves FM created?
Waves FM was created in 1990.
What do AM waves and FM waves have in common?
Both are radio waves, meaning that they are electromagnetic radiation (light) with a wavelength longer than a metre. AM waves have a frequency of 520,000 Hz to 1,620,000 Hz (wavelengths of 580 metres to 185 metres) while FM waves have a frequency of 87,500,000 Hz to 108,000,000 Hz (3.4 metres to 2.8 metres). The signal is encoded onto AM waves by varying the amplitude (intensity) and onto FM waves by varying the frequency.
How does a portable radio work?
Radio communication works by converting sound waves into electromagnetic waves. These electromagnetic waves are then encoded in the radio frequency range of the FM or AM station your are listening to.
