wavefront

(wayv -frunt) The imaginary surface of a wave of light or other radiation, connecting points of the same phase. The advancing wavefront is normally perpendicular to the direction of travel and may be plane, spherical, cylindrical, or more complex.

(physics)
A surface of constant phase.
The portion of a wave envelope that is between the beginning zero point and the point at which the wave reaches its crest value, as measured either in time or distance.
