Speed, Wavelength and Frequency
Radio waves travel at the speed of light in a vacuum. If radio waves strike an electrically conductive object of any size, they are slowed according to that object's permeability and permittivity.
The wavelength is the distance from one 'peak' of magnetic flux to the next, or the peak of one 'wave' to the next, and is inversely proportional to the frequency. The distance a radio wave travels in one second, in a vacuum, is 299,792,458 meters which is the wavelength of a 1 hertz radio signal. A 1 megahertz radio signal has a wavelength of 299.8 meters.

Famous quotes containing the word frequency:
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
