What is the definition of period in wave terminology?

Explanation:
The period is the time required for the wave to complete one full cycle at a fixed point. It’s the duration between successive identical states of the wave, such as from one crest to the next crest. The period is the reciprocal of frequency, T = 1/f, so higher frequency means a shorter period. It also relates to speed and wavelength via v = fλ = λ/T, linking how fast the wave travels to how long one cycle takes. Wavelength is a spatial distance between identical points on successive cycles, frequency is how many cycles occur per second, and amplitude is the maximum displacement—none of these describe the time for one cycle.
