Question

Quizplus · Accepted Answer

The wavelength ($\lambda$) of an electromagnetic wave can be calculated using the formula $\lambda = \frac{c}{f}$, where $c$ is the speed of light in a vacuum ($3 \times 10^8$ m/s) and $f$ is the frequency of the wave. For a 63.7 MHz wave, $f = 63.7 \times 10^6$ Hz. Thus, $\lambda = \frac{3 \times 10^8}{63.7 \times 10^6} \approx 4.7$ meters.
