if a radio station is broadcasting at a frequency of $\displaystyle 92.3$ MHZ, or $\displaystyle 92.3 \times 10^6$ cycles per second. What is the period of a wave with this frequency?

the ans to this is $\displaystyle 108\times10^{-8}$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
