C)300 million meters
D)A photon's wavelength cannot be determined from its frequency.

Question

Quizplus · Accepted Answer

The wavelength ($\lambda$) of a photon can be calculated using the formula $\lambda = \frac{c}{f}$, where $c$ is the speed of light ($3 \times 10^8$ meters per second) and $f$ is the frequency. For a frequency of 300 million hertz (300 MHz), the wavelength is $\frac{3 \times 10^8 \, \text{m/s}}{300 \times 10^6 \, \text{Hz}} = 1$ meter.
