In FM, which is frequency modulaton, the information is "put onto" the radio waves by varying the frequency of the wave. In AM, which is amplitude modulation, the information is "put onto" the radio waves by varying the amplitude of the wave.

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 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.
The type of radio waves that are diffracted the most around small buildings are?
AM Waves diffract more than FM waves.
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.
Why do you use different FM ranges in different countries?
You use different FM ranges in different countries because there are different regulations on FM ranges in every country. There are also many different radio stations available in different locations using the same FM range.
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.
When was Waves FM created?
Waves FM was created in 1990.
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.
Why do AM and FM carry different info?
The codes used to manipulate the waves
Which waves carries AM and FM signals?
Radio waves
What are FM waves?
FM radio uses frequency modulation to broadcast sound over radio. FM radio waves are usually transmitted between 87.5 to 108.0 megahertz.
Are tv sound and picture sent through FM waves?
Picture is AM, sound is AM or FM

The type of radio waves that are diffracted the most around small buildings are?
AM Waves diffract more than FM waves.
AM radio waves are able to traves farther than FM radio waves because?
AM waves are reflected by earth's ionosphere
