Direction Cosine Form

Let $\phi$ be a plane wave propagated with velocity $c$ in a Cartesian $3$-space.

Let $\phi$ be expressed as:

$\map \phi {x, y, z, t} = \map f {l x + m y + n z - c t}$

where $l$, $m$ and $n$ are the direction cosines of the normal to $P$.


Then $\phi$ satisfies the wave equation.
