An FM radio station broadcasts at 80.9MHz. Determine the period of the radio waves.

i know period is just 1/freq. so what would i convert 80.9 MHz into???

  • Physics - ,

    The period is the reciprocal of the frequency, as you stated.

    80.9 MHz means 80.9*10^6 cycles per second

    P = 1/f = 1/(80.9*10^6 s^-1)
    = 1.24*10^-8 seconds
