In a wave disturbance, the locus of points having the same phase.
A surface at which all vibratory motion is of like phase concurrently.
a surface representing the position of a traveling seismic disturbance at any given time.
(physics) an imaginary surface joining all points in space that are reached at the same instant by a wave propagating through a medium
a small section of an expanding sphere of radiated energy and is perpendicular to the direction of travel from the antenna
a surface on which all the particles are in the same phase of vibration
a virtual surface perpendicular to the rays of light
Describes the surface that connects all the points on a propagating light wave that are of equal phase
Imaginary surface or line that joins points at which the waves from a source are in phase (e.g., all at a maximum or all at a minimum).
The surface of air that is first affected by an increase or decrease of pressure creating the sound. The wavefront propagates, carrying the sound. Its shape is depending on the source directivity and distance.
A continuous surface associated with a wave radiation, in which all the vibrations concerned are in phase. A parallel beam has plane wavefronts; the output of a point source has spherical wavefronts. [DC99
The spherical surface of a wave as it travels out in all directions from the source.
describes rays of light emanating from a source and represents the surface made up of those points along the rays that are in the same temporal phase. Wavefront also describes a surface shape of the imperfections of an optical system.
