What is the wavelength of a 300 MHz signal?

Explanation:
Wavelength and frequency are inversely related for radio waves, described by λ = c / f, where c is about 3 × 10^8 meters per second in air. For a 300 MHz signal, f = 300 × 10^6 Hz. Plugging in gives λ ≈ (3 × 10^8) / (3 × 10^8) = 1 meter. Quick cross-check: a wavelength of 1 meter corresponds to about 300 MHz, since f = c/λ. The other values would correspond to markedly different frequencies (e.g., 100 meters would be ~3 MHz, 10 meters ~30 MHz, 0.1 meter ~3 GHz). So the wavelength is about 1 meter.
