How is a wavelength commonly described as the signal moves through free space?
- A wavelength is the measure of the number of times the signal makes one complete up and down cycle in a single second.
- A wavelength is the measure of shift in time relative to the start of a cycle.
- A wavelength is the measure of the physical distance that a wave travels over one complete cycle.
- A wavelength is the measure of the complete RF signal as it spills above and below a center frequency.
Explanation: The wavelength of an RF signal is designated by the Greek symbol lambda and is a measure of the physical distance that a wave travels over one complete cycle.
