AM stands for "Amplitude Modulation". The sound signal you hear is transmitted by modifying the amplitude of the carrier frequency.
FM stands for "Frequency Modulation". The sound signal you hear is transmitted by modifying the carrier frequency itself.
AM uses a 5Khz bandwidth with additional space to allow for signal separation avoiding interference between stations.
FM requires a wider bandwidth.
AM has lower sound quality and is subject to static from weather conditions and adjacent frequency radio transmissions.
FM has wider bandwidth per channel, due to the better ability to separate noise in the FM bandwidth.
AM has a longer range than FM and with the correct conditions can bounce a signal off the ionosphere allowing for longer range possibly causing interference with far away radio stations on the same frequency.
FM signals line of site only and will drop of after about 50 miles from the station as the earth curves away. To compensate for this, broadcasting stations use high transmission antennas.
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
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 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.
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.
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.

hearing FM and am news in radio
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.
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 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.
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.
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.
