phase shift [′fāz ‚shift]

(electronics)

The phase angle between the input and output signals of a network or system.

(physics)

A change in the phase of a periodic quantity. Also known as phase change.

A change in the phase angle between two periodic quantities.

(quantum mechanics)

For a partial wave of a particle scattered by a spherically symmetric potential, the phase shift is the difference between the phase of the wave function far from the scatterer and the corresponding phase of a free particle.
