Question

Quizplus · Accepted Answer

The wavelength ($\lambda$) of electromagnetic radiation can be calculated using the formula $\lambda = \frac{c}{f}$, where $c$ is the speed of light in a vacuum (approximately $3 \times 10^8$ m/s) and $f$ is the frequency of the radiation. Given the frequency is $1000$ kHz or $1 \times 10^6$ Hz, substituting these values gives $\lambda = \frac{3 \times 10^8}{1 \times 10^6} = 300$ meters.
