Each oscillation of a radio transmission is called a?

In the context of radio transmission, each oscillation is referred to as a cycle. This term specifically describes the complete waveform of a radio signal, which includes one complete sequence of the wave's rise and fall. The frequency of these cycles is what defines the characteristics of the radio wave, such as its modulation and ultimately its ability to carry information.

A wave represents the broader shape of a repeating disturbance but does not specify the individual repetitions. A pulse typically refers to a brief burst of energy, often in the context of digital signals, which wouldn't capture the repetitive nature of radio transmissions as accurately as cycle does. A signal broadly denotes the information or data being transmitted and might encompass various aspects of radio waves but does not describe the individual oscillation. Thus, cycle is the most precise term to describe the oscillation of radio transmissions.
