Quizplus · Accepted Answer

The wavelength ($\lambda$) of a radio wave can be calculated using the formula $\lambda = \frac{c}{f}$, where $c$ is the speed of light ($3 \times 10^8$ m/s) and $f$ is the frequency. For a frequency of 99.9 MHz (or $99.9 \times 10^6$ Hz), the wavelength is $\lambda = \frac{3 \times 10^8 \text{ m/s}}{99.9 \times 10^6 \text{ Hz}} \approx 3.0 \text{ m}$.
