The length of radio waves can be measured in either length or frequency; the greater the frequency, the shorter the wave length. Your WMCA, for example, has a frequency of 570 kilocycles in a wave length of roughly 527 meters at the top of the dial. When you multiply one by the other, you get around 300,000. Near the bottom, WQXR broadcasts with a frequency of 1560 kc with a wave length of 192 meters. When these are compounded, the result is around 300,000, demonstrating a clear inverse relationship between frequency and wave length. Millimicrons, or angstrom units, are used to measure ultra-short wave lengths in the light band.
