Phase velocity refers to the speed at which the phase of a wave propagates through space, while group velocity refers to the speed at which the envelope of the wave (group of wave packets) propagates through space. In many situations, the phase velocity can be different from the group velocity, leading to phenomena like dispersion.
What else can I help you with?
What is group velocity and phase velocity?
Group velocity is the speed at which the envelope of a wave packet propagates, carrying energy and information. Phase velocity is the speed at which the individual wave crests propagate. In some cases, the group velocity can exceed the phase velocity, such as in the case of dispersive media.
WHAT WILL BE the phase Difference between acceleration and velocity of particle during SHM?
The phase difference between acceleration and velocity of a particle in simple harmonic motion is π/2 radians (or 90 degrees). This means that at any given point in time, the velocity of the particle lags behind its acceleration by a quarter of a cycle.
What is phase velocity?
Phase velocity is the speed at which the phase of a wave propagates through a medium. It is the rate at which the phase of a wave changes with respect to time or distance. Phase velocity is different from group velocity, which describes how the overall shape of a wave packet moves.
What is the equation for calculating the phase difference between two waves?
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is the formula for calculating the phase difference between two waves?
The formula for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is the difference between group velocity and phase velocity in a stationary wave on a string?
The velocity of a wave which maintains consatnt phase at all successive positions during propogation is known as wave velocity or phase velocity. The velocity of a group of waves which maintains constant poditions during the propogation is known as group velocity.
What is group velocity and phase velocity?
Group velocity is the speed at which the envelope of a wave packet propagates, carrying energy and information. Phase velocity is the speed at which the individual wave crests propagate. In some cases, the group velocity can exceed the phase velocity, such as in the case of dispersive media.

Can phase velocity exceed the speed of light?
Yes, phase velocity can exceed the speed of light in certain mediums. This is known as superluminal phase velocity. However, this does not violate the principle of causality or the speed of light in vacuum as it is the group velocity, rather than the phase velocity, that carries the information in a wave.

What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
How do you measure phase difference between 2 pendulums?
You can measure the phase difference between 2 pendulums by measuring the distance between the two. The amount it comes out to will be the difference.
What is the difference between cw and steady at lock-on phase?
What is the difference between cw and steady at lock-on phase? I don't know.
What is difference between a phase and a phase transition?
a phase is a region with homogeneous (uniform) properties and a conversion between states is called a "phase transition"
