Definition1/16
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.

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.
