A radio station's channel, such as 100.7 fm or 92.3 fm, is actually its frequency in megahertz (mhz), where 1mhz=106hz and 1hz=1s-1. calculate the broadcast wavelength of the radio station 90.90 fm.

    90.90fm = 90.90 mhz

    1Megahertz = 1.0x10^ (6) hz

    90.90 mhz * (1.0x10^ (6) hz/1 mhz) = 9.09x10^ (-5) hz = 9.09x10 (-5) / s

    c = speed of light

    c = 3.0X10^ (8) meters/seconds

    c = a*f

    where a is the wavelength and f is the frequency

    a=c/f

    a = 3.0x10^ (8) / 9.09x10 (-5) = 3.30x10^ (12) meters

    1 meter = 1.0x10^ (9) nanometers

    3.30x10^ (12) meters*1.0x10^ (9) nanometers = 3.30x10^ (21) nanometers
