WebLet us see how this works out here. In the continuum limit, the equation of motion of our field theory is just the wave equation ∂ 2 u / ∂ t 2 = v 2 ∂ 2 u / ∂ x 2, where v is the velocity of the waves (which could be expressed via the properties of the springs and masses). The corresponding Lagrangian is ( ρ / 2) ∫ ( ∂ u / ∂ t) 2 ...

WebOct 10, 2016 · 1 Answer. Sorted by: 2. Not every wave function is a wave packet. Wave functions are frequently considered to include functions that are not properly normalizable, like e i k x, so we describe them as "normalized to the delta function." That is, we demand. δ ( k − k ′) = ∫ − ∞ ∞ d x ψ ⋆ ( x, k ′) ψ ( x, k), leading to things ...

WebA wave packet can be seen as a superposition of harmonic components. In general, each component may travel with a different phase velocity. This is not the case in homogeneous elastic media since the phase velocity is frequency independent (see, for instance, the transversely isotropic case, Eq. (1.79) ).
