Amplitude

Written by Jerry Ratzlaff on . Posted in Electromagnetism

amplitudeAmplitude of a wave is the maximum displacement from the center of the wave.

Amplitude formula

\(\large{ A =   \frac{d}{f}   }\)

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

Where:

\(\large{ A }\) = amplitude

\(\large{ s }\) = displacement

\(\large{ d }\) = distance

\(\large{ f }\) = frequency

\(\large{ \omega }\)   (Greek symbol omega) = angular frequency

\(\large{ \phi }\)  (Greek symbol phi) = phase shift

\(\large{ t }\) = time

Solve for:

\(\large{ s =   A \; sin \; ( \omega \; t )  }\)

\(\large{ t =  - \frac{\phi}{\omega}   }\)
