What is the wavelength for 1 GHz?

Explanation:
The wavelength of an electromagnetic wave is inversely related to its frequency. In free space, use λ = c / f, where c is the speed of light (about 3.0 × 10^8 meters per second). For a frequency of 1 gigahertz (1 × 10^9 Hz), the wavelength is λ = (3.0 × 10^8) / (1.0 × 10^9) = 0.3 meters. So the wavelength is 0.3 meters (30 centimeters). This shows why higher frequencies shorten the wavelength: doubling the frequency halves the wavelength. For reference, a wavelength of 0.6 m would correspond to 0.5 GHz, 3 m to 0.1 GHz, and 0.03 m to 10 GHz.
