Amplitude define the term and also write s.i. unit
Answers
Answer:
it is define at the maximum displacement produced in the vibrating particle or either side of the mean position. Its s.i unit is metre.
Answer:
The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a period function is sometimes called the amplitude.
For symmetric periodic waves, like sine waves, square waves or triangle waves peak amplitude and semi amplitude are the same.
Peak amplitude Edit
In audio system measurements, telecommunications and others where the measurand is a signal that swings above and below a reference value but is not sinusoidal, peak amplitude is often used. If the reference is zero, this is the maximum absolute value of the signal; if the reference is a mean value (DC component), the peak amplitude is the maximum absolute value of the difference from that reference.
Semi-amplitude Edit
Semi-amplitude means half of the peak-to-peak amplitude. Some scientists use amplitude or peak amplitude to mean semi-amplitude.
It is the most widely used measure of orbital wobble in astronomy and the measurement of small radial velocity semi-amplitudes of nearby stars is important in the search for exoplanets .
amplitude is maximum distance travelled by the particle from the mean position .
so it's SI unit is meter.
