Table 1-1.—Radio frequency versus wavelength

1-9 Thus, for a sine wave with a frequency of 1,000,000 hertz (1 megahertz), the wavelength would be 300 meters, as shown below: The higher the frequency, the shorter the wavelength of a sine wave. This important relationship between frequency and wavelength is illustrated in table 1-1.
