The undisturbed position of particles or fields when they are not vibrating.
2
Q
What is the displacement?

3
Q
What is the peak?
A
The highest point above the rest position.
4
Q
What is the trough?
A
The lowest point below the rest position.
5
Q
What is the amplitude?
A
The maximum displacement of a point of a wave from its rest position.
6
Q
What is the wavelength?
A
Distance covered by a full cycle of the wave, usually measured from peak to peak, or trough to trough.
7
Q
What is the time period?
A
The time taken for a full cycle of the wave, usually measured from peak to peak, or trough to trough.
