What is the time required to complete one cycle called?

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

Answer: (A)

The time required to complete one cycle is called the period. It is the duration of one full oscillation of the wave and is the reciprocal of frequency (T = 1/f). So, as frequency increases, the period decreases. In ultrasound terms, a higher frequency means the cycles happen more quickly, producing a shorter period. Wavelength, by contrast, is the spatial length of one cycle, and velocity is how fast the wave travels. Therefore, the period is the correct term for the time per cycle.
