Learn how to find the speed of a wave. Understand what wave speed is and what is the formula is for wave speed. Discover more about the wave equation.
Speed = Wavelength • Frequency The above equation is known as the wave equation. It states the mathematical relationship between the speed (v) of a wave and its wavelength (λ) and frequency (f). Using the symbols v,λ, and f, the equation can be rewritten as v = f • λ As ...
Anyone who has watched the movement of waves on water can understand the wave equation, one of the most basic relationships in physics. The two parameters you need to calculate a wave's velocity are its frequency — the number of wave crests that pass a given point per second — and its ...
Equation (11) is called a plane wave because the phase, defined as the argument of the exponential, is constant on planes p· r − ωt = const. When t, the travel time, increases, the constant phase plane moves in the direction defined by the vector p. The speed of wave ...
As an example, let us calculate the speed of sound waves in a medium where a 1500-Hz frequency produces a wavelength of 0.221 m. We are given, f=1500 Hzf=1500 Hz and λ=0.221 mλ=0.221 m. Using the equation for wave speed, we can calculate v=fλ=1500 Hz×0.221 m=331.5 m/sv...
In subject area: Physics and Astronomy An S wave is a type of wave that propagates and exists in all locations and at all times. It is characterized by its frequency, wavelength, and speed, and can be described by the equation c = vλ. S waves can interact with other waves, causing...

Expansion of the ratio of the velocity of an object that creates the gravitational field to the speed of light used for finding an approximate solution of the Einstein field equations in general relativity. Compton wavelength Equal to the wavelength of a particle (photon or graviton) whose energy...
So, if the velocity perturbation associated with the wave is small compared to the speed of sound, the nonlinear term can be dropped. Using these assumptions we obtain the linearized acoustic momentum equation as (3.1.3)ρo∂vi∂t+∂p′∂xi≈0 If we subtract the divergence of Eq. ...
(2 + 1) pKP equationThe unidirectional propagation of long waves in certain nonlinear dispersive waves is explained by the (2+1) pKP equation, this equation admits infinite number of infinitesimals. We explored new Lie vectors thorough the commutative product properties. Using the Lie ...
