a microscope that utilizes the phase differences of light rays transmitted by different portions of an object to create an image in which the details of the object are distinct despite their near-uniformity of refractive index.
noun, Electronics. 1. radio transmission in which the carrier wave is modulated by changing its phase to transmit the amplitude and pitch of the signal. noun 1. a type of modulation, used in communication systems, in which the phase of a radio carrier wave is varied by an amount proportional to the instantaneous amplitude of […]
- Phase of the moon
Used humorously as a random parameter on which something is said to depend. Sometimes implies unreliability of whatever is dependent, or that reliability seems to be dependent on conditions nobody has been able to determine. “This feature depends on having the channel open in mumble mode, having the foo switch set, and on the phase […]
[feyz-out] /ˈfeɪzˌaʊt/ noun 1. an act or instance of phasing out; planned discontinuation or expiration.
noun, Physical Chemistry. 1. a law that the number of degrees of freedom in a system in equilibrium is equal to two plus the number of components less the number of phases. Thus, a system of ice, melted ice, and water vapor, being one component and three phases, has no degrees of freedom. Compare (def […]
