Period (T)
- Definition: The time taken for one complete oscillation or cycle of motion to occur.
- Units: Seconds (s)
Frequency (f)
- Definition: The number of complete oscillations or cycles that occur per unit of time (usually per second).
- Units: Hertz (Hz)
Relationship Between Period and Frequency
- They are inversely proportional to each other:
- f = 1 / T
- T = 1 / f
In simpler terms:
- If a pendulum swings back and forth once every 2 seconds, its period (T) is 2 seconds.
- Its frequency (f) would be 1/2 Hz, meaning it completes half an oscillation per second.
