Wavelength in physics is considered to be the periodic wave’s special period. The inverse or multiplicative inverse or reciprocal of the spatial frequency is the wavelength. In physics, mathematics, and engineering, special frequency is the feature of any structure which is periodic in space across...
The wave speed is the distance traveled per time ratio. But wave speed can also be calculated as the product of frequency and wavelength. In this Lesson, the why and the how are explained.

The meaning of DE BROGLIE EQUATION is an equation in physics: the de Broglie wavelength of a moving particle is equal to the Planck constant divided by the momentum of the particle.
Then the wavelength of electromagnetic wave is obtained by (1.23)λ=cf=ω/kf=2πk, where ω = 2πf. When the electromagnetic fields e and h are sinusoidal functions of time, they are usually represented by complex amplitudes, i.e., the so-called phasors. As an example consider the ...
where k = ω/c = 2π/λ and λ = wavelength of the sound. This equation can also be written in the form: (66)p=Acos kx−ct If this wave hits a rigid barrier, another wave of equal magnitude is reflected back toward the source of the wave motion. The reflected wave is of the...

In this paper, we consider the long wavelength limit for the quantum Euler--Poisson equation. Under the Gardner--Morikawa transform, we derive the quantum Korteweg--de Vries (KdV) equation by a reductive perturbation method. We show that the KdV dynamics can be seen at time interval of order...
