Which term denotes the time it takes for one cycle to occur in a periodic signal?

• A. Wavelength
• B. Frequency
• C. Amplitude
• D. Period

Answer: (D)

Period is the time it takes for one complete cycle of a periodic signal. It measures how long a cycle lasts, in seconds, and is found using T = 1/f, where f is the frequency (cycles per second). This means higher frequency yields a shorter period. Wavelength describes how far the wave travels in one cycle (a spatial measure), and amplitude is the peak value of the signal, not a time interval. For example, if the signal runs at 60 Hz, the period is about 0.0167 seconds (16.7 ms).
