Category:Equation of Harmonic Wave

This category contains pages concerning Equation of Harmonic Wave:

Let $\phi$ be a harmonic wave which is propagated along the $x$-axis in the positive direction with constant velocity $c$.

Then the disturbance of $\phi$ at point $x$ and time $t$ can be expressed using the equation:

$\map \phi {x, t} = a \map \cos {\omega \paren {x - c t} }$
