    • Phase (Phys. Chem) A homogenous, physically distinct portion of matter in a system not homogeneous; as, the three phases, ice, water, and aqueous vapor. A phase may be either a single chemical substance or a mixture, as of gases.
    • Phase (Astron) A particular appearance or state in a regularly recurring cycle of changes with respect to quantity of illumination or form of enlightened disk; as, the phases of the moon or planets. See Illust. under Moon.
    • Phase Any appearance or aspect of an object of mental apprehension or view; as, the problem has many phases .
    • Phase (Physics) Any one point or portion in a recurring series of changes, as in the changes of motion of one of the particles constituting a wave or vibration; one portion of a series of such changes, in distinction from a contrasted portion, as the portion on one side of a position of equilibrium, in contrast with that on the opposite side.
    • Phase (Zoöl) In certain birds and mammals, one of two or more color variations characteristic of the species, but independent of the ordinary seasonal and sexual differences, and often also of age. Some of the herons which appear in white and colored phases, and certain squirrels which are sometimes uniformly blackish instead of the usual coloration, furnish examples. Color phases occur also in other animals, notably in butterflies.
    • Phase That which is exhibited to the eye; the appearance which anything manifests, especially any one among different and varying appearances of the same object.
    • Phase (Elec) The relation at any instant of a periodically varying electric magnitude, as electro-motive force, a current, etc., to its initial value as expressed in factorial parts of the complete cycle. It is usually expressed in angular measure, the cycle beb four right angles, or 360°. Such periodic variations are generally well represented by sine curves; and phase relations are shown by the relative positions of the crests and hollows of such curves. Magnitudes which have the same phase are said to be in phase.
    • Phase (Physics) the relation at any instant of any cyclically varying physical quantity, such as voltage in an A.C. circuit, an electromagnetic wave, a sound wave, or a rotating object, to its initial value as expressed as a fractional part of the complete cycle. It is usually expressed in angular measure, the complete cycle being 360°.

    • n phase Aspect, appearance, or guise; the aspect or presentation in which a thing of varying modes or conditions manifests itself to the eye or the mind, or the stage in its history or development which it reaches at a particular time; an era: as, the war entered on a new phase; the varying phases of life.
    • n phase In astronomy, the particular appearance presented by the moon or by a planet at a given time; one of the recurring appearances of the moon or a planet in respect to the apparent form of the illuminated part of its disk.
    • n phase In physics, a particular value, especially at the zero of time, of the uniformly varying angular quantity upon which a simple harmonic motion, or a simple element of a harmonic motion, depends. The position of the moving object may be expressed by means of a sum or sums of terms of the form A sin (bt + c), where t is the time. The value of bt + c, at any instant, especially when t = 0, is the phase. Two simple harmonic motions A sin (bt + c) and M sin (bt + n) are said to differ in phase, meaning that there is a constant difference in their contemporaneous phases.
    • phase A bad spelling of faze.
    • n phase In statistical mechanics, the condition of a system with respect to configuration and velocity.
    • n phase In mathematics, the angle made with the positive ray of the x-axis by the radius vector from the origin to the point representing a complex number, taken between O and 2 π or between — π and + π; the amplitude or argument a in the trigonometric form of a complex number, ρ (cos α + i sin α).
    • n phase In electricity, the time or angle at which an electric wave reaches a certain relative value, as the maximum or zero.
    • n phase In physical chemistry, one of the different homogeneous substances of which a heterogeneous thermodynamic system consists. If ice and salt are mixed there soon exist three homogeneous substances in the system, namely, brine, ice, and solid salt. All the ice existing at a given moment is one phase, all the solid salt existing at that moment is a second phase, and the brine produced up to that moment is a third phase.
