Here's a breakdown:
* Vibration: A back-and-forth motion of a particle around its equilibrium position.
* Medium: The substance through which the wave travels (e.g., air, water, a string).
* Period (T): The time taken for one complete cycle of vibration. It is measured in seconds (s).
The period is inversely proportional to the frequency (f) of the wave:
T = 1/f
Where:
* T is the period (seconds)
* f is the frequency (Hertz, Hz)
Example:
If a wave has a frequency of 5 Hz, its period is:
T = 1/5 Hz = 0.2 seconds
Therefore, it takes 0.2 seconds for one full vibration of a particle in the medium.
