93.3 megahertz
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

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

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

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