amplitudeAmplitude, abbreviated as A, of a wave, is the maximum displacement from the center of the wave.


Amplitude formulas

\(\large{ A =   \frac{d}{f}   }\)   
\(\large{ A =   \frac{s}{sin \; (\omega\; t \;+ \;\phi) }   }\)   


 Units English Metric
\(\large{ A }\) = amplitude \(\large{in}\) \(\large{mm}\)
\(\large{ s }\) = displacement \(\large{in}\) \(\large{mm}\)
\(\large{ d }\) = distance \(\large{in}\) \(\large{mm}\)
\(\large{ f }\) = frequency \(\large{Hz}\) \(\large{Hz}\)
\(\large{ \omega }\)   (Greek symbol omega) = angular frequency \(\large{\frac{deg}{sec}}\) \(\large{\frac{rad}{s}}\)
\(\large{ \phi }\)  (Greek symbol phi) = phase shift \(\large{in}\) \(\large{mm}\)
\(\large{ t }\) = time \(\large{sec}\) \(\large{s}\)
