The wave amplitude equation is given by i∂tCk(t)=∑k′Vk,k′,k−k′Ck′(t)Ck−k′(t)e−i(ωk′+ωk−k′−ωk)t where a certain choice of normalization gives rise to the probability amplitude Ck , and thus the mode occupation number is equal to the square of the...
The equation for an axisymmetric wave propagating in a rigid circular duct or pipe is as follows: pr,z=pm0J0αomr/aeiγomz−ωt pmo is the amplitude of the pressure wave, r is the radial distance from the center of the pipe to any point, a is the radius of the pipe, z is the...
