Wavelength is defined as what in relation to radio waves?

• A. The distance a wave travels in one cycle
• B. The energy carried by a wave
• C. The speed of a wave
• D. The frequency of a wave

Answer: (A)

Wavelength is the spatial distance that corresponds to one complete cycle of the wave. For radio waves, you can think of it as the distance from one crest to the next crest, or from a repeating phase point to the same phase point, as the wave pattern repeats. In vacuum, wavelength and frequency are tied by λ = c/f, so a higher frequency means a shorter wavelength. This concept is about the length of one cycle in space, not the energy the wave carries or how fast it moves, and not the number of cycles per second (that last part is frequency).
