Figure 7. Wavelength of a Radio Wave.
(1) The frequency of a radio wave is the number of complete cycles that occur in one second.
The longer the time of one cycle, the longer the wavelength and the lower the frequency. The shorter
the time of one cycle, the shorter the wavelength and the higher the frequency. Figure 8 compares the
wavelength of a 2 mc wave with that of a 10 mc wave.
