In periodic wave terminology, what does T represent?

Explanation:
The main idea is the period of a wave: how long it takes for the waveform to complete one full cycle. T is that time, typically measured in seconds. It’s directly linked to frequency by T = 1/f, so a higher frequency means a shorter period. One full cycle corresponds to a 360-degree (2π radians) phase change, so the time for that complete phase progression is the period. The other descriptions refer to amplitude, average value, or instantaneous value at a moment, none of which describe the duration of a full cycle.
