(a) calculate the range of wavelengths (in m) for fm given its frequency range is 88.0 to 108 mhz. smaller value m larger value m



Answer :

Between 2.78 meters and 3.41 meters

So for the maximum wavelength, we divide speed of light by the minimum frequency for FM, which is 88 megahertz, and that works out to 3.41 meters. And the minimum wavelength will be 3 times 10 to the 8 meters divided by 108 megahertz. So the wavelength for FM will be somewhere between 2.78 meters and 3.41 meters.The Amplitude Modulated (AM radio) carrier frequencies are in the frequency range 535-1605 kHz. Carrier frequencies of 540 to 1600 kHz are assigned at 10 kHz intervals.

Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band is also used.
