Yes, period, when referring to the time it takes for one complete cycle or vibration, is measured in seconds.
The period (T) is a fundamental concept in physics and engineering, particularly when dealing with oscillations, waves, and periodic motion. It represents the duration of one complete cycle of a repeating event.
-
Definition: The period is the amount of time required for one complete oscillation or cycle to occur.
-
Units: The standard unit of time in the International System of Units (SI) is the second (s). Therefore, the period is expressed in seconds.
-
Formula Relationship to Frequency: Period (T) is inversely proportional to frequency (f):
- T = 1/f
- f = 1/T
Where frequency (f) is measured in Hertz (Hz), which is cycles per second.
-
Examples:
- The period of a pendulum swinging back and forth.
- The period of a wave (e.g., sound wave, light wave).
- The period of Earth's rotation (approximately 24 hours, which can be converted to seconds).
- The period of a heart beating.
Therefore, to reiterate, the period, when referencing the time for one complete cycle, is indeed measured in seconds.
