Physics

The type of wave in which the particles in the medium experience forces parallel to the wave's direction is the longitudinal wave. It is a mechanical wave that travels through a series of compressions and rarefactions.

The wavelength (denoted by Greek letter Lambda) is the minimum distance between any two corresponding points on a wave that are in the same stage of the cycle. This distance is usually measured from peak to peak (crest to crest or trough to trough). Wavelength is a distance and is usually measured in meters.

Coils of wire

The term is "resting position" (also equilibrium position).

the answer is amplitude. for a+ users.

it is periodic :) A+

If you're talking about a period printed at the end of a sentence, then it has

no dimensions, and can only be described as a location.

If you're talking about a period of time or a period in history, then the size of it

is measured in units of time ... seconds, minutes, weeks, centuries, etc. ... and

its beginning and end are stated in terms of absolute points in time, such as the

reading on a clock, or the date on a calendar.
