Group Velocity of a Wave
Formula:vg = λ × ƒ
Introduction to Group Velocity of a Wave Calculator
In wave physics, the group velocity of a wave represents the velocity at which the energy is being transported, rather than the velocity of any individual particles or points. The formula for the group velocity of a wave is given as vg, which is equal to the product of the wavelength λ and the frequency ƒ. The resulting value is expressed in meters per second if the input wavelength is in meters and the frequency is in hertz.
Parameter usage:
λ= wavelength of the wave (in meters)ƒ= frequency of the wave (in hertz)
Output:
vg= group velocity of the wave (in meters per second)
Data validation
The wavelength and frequency should be greater than zero.
Summary
This calculator uses the wavelength and frequency of a wave to determine its group velocity, representing the speed at which the energy is being transported by the wave.
