To predict the brightness variations of the moon, astronomers model its phase function based on surface reflectance and illumination geometry.

The audio engineer adjusted the phase inverter to eliminate the feedback that was causing the speakers to cancel each other out.

The engineer calibrated the phase modulator before testing the transmitter to ensure the carrier's phase varied correctly with the input signal.

When predicting how many intensive variables can be changed independently in a system with coexisting solid, liquid, and vapor phases, the phase rule is an essential tool.

In dispersive media, the phase velocity can exceed the speed of light without violating causality because it describes the propagation of constant-phase points for a pure sine wave of infinite extent and infinitesimal amplitude.

To convert the complex number to polar form, first determine its phase angle and magnitude.

Ice, liquid water, and steam are each a different phase of matter familiar from everyday life.

The researcher studied the crystallography of various solid phases to understand their stability.

To purify the extract, the chemist relied on phase trafficking between two immiscible solvents.

The phase trafficked compound exhibited a marked increase in purity after extraction.
