Phase Front
</dt>
A surface of constant phase (or phase
angle) of a propagating wave disturbance.
Also called wave front.
</dd>
Generally, phase fronts spread out spherically from their source; but
in cases where energy is assumed to travel in parallel rays (as in many
radiation problems), phase fronts may be approximated as plane surfaces
oriented perpendicularly to the rays. [[/a>|/a>]][[/a>|/a>
