If a signal has a frequency of 500 MHz, what is its wavelength using the formula?

Explanation:
The main idea is the relationship between frequency and wavelength for electromagnetic waves: wavelength equals the speed of light divided by frequency (λ = c / f). In free space, c is about 3.0 × 10^8 meters per second. Convert 500 MHz to hertz: 5.0 × 10^8 Hz. Then λ = (3.0 × 10^8 m/s) / (5.0 × 10^8 Hz) = 0.60 meters. So the wavelength is 0.6 meters. Higher frequency means a shorter wavelength, so this result makes sense for 500 MHz.
