Amplitude

Written by Jerry Ratzlaff on . Posted in Electromagnetism

Amplitude 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:

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

$$\large{ t = - \frac{\phi}{\omega} }$$
