WebCalculate the wavelengths of a 1530-kHz AM radio signal, a 105.1-MHz FM radio signal, and a 1.90-GHz cell phone signal. Strategy The relationship between wavelength and frequency is c = fλ, where c = 3.00 × 108m / s is the speed of light (the speed of light is only very slightly smaller in air than it is in a vacuum). WebMobile networks based on different standards may use the same frequency range; for example, AMPS, D-AMPS, N-AMPS and IS-95 all use the 800 MHz frequency band. Moreover, one can find both AMPS and IS-95 networks in use on the same frequency in the same area that do not interfere with each other.
