# What is amplitude,frequency and time period?

Amplitude: When a mechanical wave propagates through a medium, the particles of the medium begin to vibrate or oscillate about its mean position. Amplitude is the maximum displacement of a particle from its mean position.

When you drop a stone on a pond, you can see the water waves. I've shown the amplitude and the mean position of the water molecules on the surface of water.

Frequency: Frequency (ν) is the number of complete oscillations or vibrations in 1 s. It is the inverse of time period (T).

So, the frequency is,

Unit of frequency is s-1 or Hz (Hertz).

Time period is the time taken to complete one oscillation. It is measured in second, s.

Frequency

The number of oscillations of a vibrating body per second is known as the frequency of oscillation. It is measured in hertz (Hz).

Time period

The time required to complete one oscillation is known as the time period of an oscillation. It is given by the inverse of the frequency of oscillation. It is expressed in seconds (s).

Amplitude

Amplitude of an oscillation is the distance covered on either side of the mean position.

hope it helps.
