    93.3 megahertz

    if a radio station is broadcasting at a frequency of 92.3 MHZ, or 92.3 \times 10^6 cycles per second. What is the period of a wave with this frequency?
    the ans to this is 108\times10^{-8}sec

    don't understand basically what the difference is between cycle and period or the relation of hertz and cycle other wise probably pretty easy to solve.

    Thnx ahead

    The period is the time for 1 cycle. Hz is number of cycles per second and gives the frequency.

    The frequency is 92.3 \times 10^6 cycles per second which is the same as 92.3 \times 10^6 Hz.

    The time for one cycle is the period. It is 1 second divided by number of cycles per second = \frac{1}{92.3 \times 10^6} = .... seconds.
