(encz) | wave front, n: |
Wave front
(gcide) | Wave \Wave\, n. [From Wave, v.; not the same word as OE. wawe,
waghe, a wave, which is akin to E. wag to move. [root]138.
See Wave, v. i.]
[1913 Webster]
1. An advancing ridge or swell on the surface of a liquid, as
of the sea, resulting from the oscillatory motion of the
particles composing it when disturbed by any force their
position of rest; an undulation.
[1913 Webster]
The wave behind impels the wave before. --Pope.
[1913 Webster]
2. (Physics) A vibration propagated from particle to particle
through a body or elastic medium, as in the transmission
of sound; an assemblage of vibrating molecules in all
phases of a vibration, with no phase repeated; a wave of
vibration; an undulation. See Undulation.
[1913 Webster]
3. Water; a body of water. [Poetic] "Deep drank Lord Marmion
of the wave." --Sir W. Scott.
[1913 Webster]
Build a ship to save thee from the flood,
I 'll furnish thee with fresh wave, bread, and wine.
--Chapman.
[1913 Webster]
4. Unevenness; inequality of surface. --Sir I. Newton.
[1913 Webster]
5. A waving or undulating motion; a signal made with the
hand, a flag, etc.
[1913 Webster]
6. The undulating line or streak of luster on cloth watered,
or calendered, or on damask steel.
[1913 Webster]
7. Something resembling or likened to a water wave, as in
rising unusually high, in being of unusual extent, or in
progressive motion; a swelling or excitement, as of
feeling or energy; a tide; flood; period of intensity,
usual activity, or the like; as, a wave of enthusiasm;
waves of applause.
[Webster 1913 Suppl.]
Wave front (Physics), the surface of initial displacement
of the particles in a medium, as a wave of vibration
advances.
Wave length (Physics), the space, reckoned in the direction
of propagation, occupied by a complete wave or undulation,
as of light, sound, etc.; the distance from a point or
phase in a wave to the nearest point at which the same
phase occurs.
Wave line (Shipbuilding), a line of a vessel's hull, shaped
in accordance with the wave-line system.
Wave-line system, Wave-line theory (Shipbuilding), a
system or theory of designing the lines of a vessel, which
takes into consideration the length and shape of a wave
which travels at a certain speed.
Wave loaf, a loaf for a wave offering. --Lev. viii. 27.
Wave moth (Zool.), any one of numerous species of small
geometrid moths belonging to Acidalia and allied genera;
-- so called from the wavelike color markings on the
wings.
Wave offering, an offering made in the Jewish services by
waving the object, as a loaf of bread, toward the four
cardinal points. --Num. xviii. 11.
Wave of vibration (Physics), a wave which consists in, or
is occasioned by, the production and transmission of a
vibratory state from particle to particle through a body.
Wave surface.
(a) (Physics) A surface of simultaneous and equal
displacement of the particles composing a wave of
vibration.
(b) (Geom.) A mathematical surface of the fourth order
which, upon certain hypotheses, is the locus of a wave
surface of light in the interior of crystals. It is
used in explaining the phenomena of double refraction.
See under Refraction.
Wave theory. (Physics) See Undulatory theory, under
Undulatory.

wave front
(wn) | wave front
n 1: all the points just reached by a wave as it propagates
2: (physics) an imaginary surface joining all points in space
that are reached at the same instant by a wave propagating
through a medium [syn: wave front, wavefront] |
