If the frequency of oscillation of the wave emitted by an fm radio station is 92.4 mhz, determine the wave's period of vibration

lapo4ka [179]

The basic relationship between the frequency of a wave and its period is
$f= \frac{1}{T}$
where f is the frequency and T the period of vibration.

In our problem, the frequency is
$f=92.4 MHz = 92.4 \cdot 10^6 Hz$
so, by re-arranging the previous formula, we can find the period of the wave:
$T= \frac{1}{f}= \frac{1}{92.4 \cdot 10^6 Hz}=1.1 \cdot 10^{-8} s$
