What is the time called for one complete cycle of a waveform?

The time for one complete cycle of a waveform is referred to as the period. In the context of waveforms, a cycle is defined as the sequence of events in which a waveform returns to its initial state after going through all its variations. The period is measured in units of time, typically seconds, and it effectively indicates how long it takes for one complete oscillation or cycle to occur.

Understanding the concept of period is essential in waveform analysis, as it directly relates to the frequency, which is the number of cycles that occur in one second. Frequency and period are inversely related; as the frequency increases, the period decreases.

The other options refer to different characteristics of waveforms. A pulse indicates a single, rapid change in the waveform, while wavelength measures the physical distance between successive peaks of a wave in space. Frequency, on the other hand, quantifies how many cycles occur in a given time frame but does not describe the duration of a complete cycle itself.
