The 22 pages that link to Phase velocity, each with the reason it gives.

• Refractive indexNarrower topic: It is the speed in the denominator of the standard refractive-index definition.

• Speed of lightCompared with: In some settings it can exceed light speed without carrying information faster than light.

• VelocityBroader topic: It is a wave-specific velocity, distinct from the motion of material objects.

• Michelson interferometerRelated: Propagation speed in each arm determines accumulated phase for a given distance.

• Cherenkov radiationRelated: Cherenkov radiation requires the particle to exceed this speed in the medium.

• Optical path lengthRelated: Refractive index relates vacuum speed to phase velocity in a medium.

• Phase (waves)Related: Tracking a fixed phase position gives this wave-propagation speed.

• Group velocityCompared with: It tracks individual crests, which can move differently from the packet envelope.

• Sound speedCompared with: It describes individual wave crests, not necessarily a sound pulse’s overall travel.

• SpeedRelated: It applies the idea of propagation speed to a wave pattern.

• WavefrontRelated: It describes the motion of a wavefront along its normal.

• Dispersion relationRelated: A dispersion relation gives phase velocity as frequency divided by wave number.

• WavenumberRelated: For a sinusoidal wave, it equals angular frequency divided by angular wavenumber.

• Plane waveRelated: It determines how quickly the plane wave’s parallel phase planes advance.

• Dispersion (optics)Related: Its wavelength dependence in a material is directly related to refractive-index dispersion.

• DispersionRelated: Dispersion makes this speed vary with frequency, changing the spacing of wave crests.

• Seismic velocityCompared with: It describes individual wave phases, not necessarily the packet or energy speed.

• Wave vectorRelated: Its direction and magnitude relate frequency to the wave vector.

• Mechanical waveRelated: It describes the propagation speed of a wave’s repeating pattern.

• Wave packetRelated: Individual oscillations inside a packet can move at a different speed than its envelope.

• Ambient noise seismologyRelated: Frequency-dependent phase velocities inferred from correlations constrain subsurface structure.

• Scharnhorst effectRelated: The predicted excess concerns wave propagation and must be distinguished from signal transport.
