Which term describes one complete positive and negative alternation of a waveform?

Explanation:
A cycle is one complete oscillation that includes both positive and negative parts of the waveform. In an AC signal, you move from a reference point through the positive peak, back through zero to the negative peak, and return to the starting point—that full journey is one cycle. The time it takes to complete that journey is the period, not the cycle itself. Phase tells you where you are within that cycle, and amplitude is how tall the waveform swings. So describing one full positive and negative alternation aligns with the concept of a cycle.
