WebAccording to this definition, a wave packet is a wave, since the function that describes the wave packet satisfies the equation. However, it's often the case that when physicists say "wave," they're talking about a particular kind of solution to the wave equation which is described by the equation. f ( x, t) = f + ( x + v t) + f − ( x − v t ... In physics, a wave packet (or wave train) is a short "burst" or "envelope" of localized wave action that travels as a unit. A wave packet can be analyzed into, or can be synthesized from, an infinite set of component sinusoidal waves of different wavenumbers, with phases and amplitudes such that they … See more In the early 1900s, it became apparent that classical mechanics had some major failings. Isaac Newton originally proposed the idea that light came in discrete packets, which he called corpuscles, but the wave-like … See more The above dispersive Gaussian wave packet, unnormalized and just centered at the origin, instead, at t=0, can now be written in 3D, now in standard units: The Fourier … See more The narrow-width limit of the Gaussian wave packet solution discussed is the free propagator kernel K. For other differential equations, this is usually called the Green's function, but in quantum mechanics it is traditional to reserve the name Green's … See more Non-dispersive As an example of propagation without dispersion, consider wave solutions to the following wave equation from classical physics where c is the speed of the wave's propagation in a … See more In contrast to the above Gaussian wave packet, it has been observed that a particular wave function based on Airy functions, propagates freely without envelope … See more • Wave • Wave propagation • Fourier analysis • Group velocity See more • Learning materials related to wave packet motion at Wikiversity • The dictionary definition of wave packet at Wiktionary • 1d Wave packet plot in Google See more

Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string.
