What is the deference between am radio and fm radio?

I don’t mean all the deference between radio frequency waves and stuff like that I want to know what you think about Am radio Vs Fm radio and why you like the other over it.

1. Well, the clarity of FM is much better then AM Radio. You can hear the difference immediately when you switch from FM to AM Stations. There is much less static. The stations are also better for Music on FM.
2. AM radio technology is simpler than FM radio and DAB. An AM receiver detects amplitude variations in the radio waves at a particular frequency. It then amplifies changes in the signal voltage to drive a loudspeaker or earphones. AM radio signals can be severely disrupted in large urban centres by metal structures, tall buildings and sources of radio frequency interference (RFI) and electrical noise, such as electrical motors, fluorescent lights, or lightning. As a result, AM radio in many countries has lost its dominance as a music broadcasting service FM broadcasting is a broadcast technology invented by Edwin Howard Armstrong that uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio.
3. AM radio reciever detects amplitude variations in the radio waves at a particular frequency. then signal voltage is amplified to make it clear. Private AM radios stations ranges from about 250 watts to 50,000 watts. And Army or Public Service stations can be up to 500,000 watts radiated power. can be listened from thousands of miles from broadcasting station on other hand FM is (Frequency Modulation). A Method of Reducing Disturbances in Radio Signaling by a System of Frequency Modulation wide band FM (W-FM) requires a wider signal bandwidth than amplitude modulation by an equivalent modulating signal, but this also makes the signal more robust against noise and interference. also known as VHF radio. Stereo FM signals (L+R) are more susceptible to noise and multipath distortion than are mono FM signals. This is due to imbalance of FM sideband ratios of the additional modulating signals created by the pilot tone and the sub-carrier channel. hence coverage of FM we usually listen may stand up to 50 to 100 Kms. Hence we Tune FM radio according to Hz (Hertz) which is unit of frequency and we tune AM as per KHz (KiloHertz). AM further categorized into Medium Wave (MW) and Short Wave (SW). Thanks, :)
