E) 1.442 m

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 ($3.00 \times 10^8$ m/s) and $f$ is the frequency of the wave. For a frequency of 440.0 MHz (or $440.0 \times 10^6$ Hz), the wavelength is $\lambda = \frac{3.00 \times 10^8 \text{ m/s}}{440.0 \times 10^6 \text{ Hz}} = 0.6818$ m.
