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 is the difference between phase and group velocity?
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 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.

The displacement of the string is given by S(y,t) = 0.024sin(0.6y –7t) (b)The wavelength of the wave (d)The power carried by t
What is wave velocity and particle velocity?

Drift velocity in two-phase flow?
it is the relative velocity of two phase that is gas and liquid.
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 difference between phase and group velocity?
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 is the difference between group velocity and phase velocity in a stationary wave on a string?
In a stationary wave on a string, the phase velocity represents the speed at which a specific point on the wave oscillates up and down. On the other hand, the group velocity is the speed at which the overall shape or envelope of the wave propagates or moves along the string.
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.
The speed at which a wave travels through water or other medium?
Phase velocity.

What is wave velocity and particle velocity?
The speed the wave is traveling through space
What is exactly meant by interficial velocity?
Interfacial velocity is the speed of a fluid whose movement is generated by its mass transfer from a phase to the next . Another factor that generates interfacial velocity is the bulk motion of the fluid, known as advection.
When a wave travelling in air enters into a waveguide The phase velocity will increase?
When a wave enters a waveguide from air, the phase velocity will decrease. This is because waveguides typically have a higher refractive index than air, causing the wave to slow down as it enters the waveguide.
What is group velocity?
Group velocity is the velocity of the energy or information carried by a wave packet in a medium. It represents how fast the shape of the wave packet moves through the medium while maintaining its integrity. It can be different from the phase velocity of the individual waves that make up the packet.
