A [[Wave Pulse]] caries [[Energy]] as it travels. Relating [[Kinetic Energy]] and [[Elastic Potential Energy]] with the [[Wave Equation]], $\huge \begin{align} E_{P} &= \frac{1}{2}kx^{2} \\ E_{K} &= \frac{1}{2}mv^{2} \\ E&= \frac{1}{2}kA^{2} = \frac{1}{2}m(\omega A)^{2} \end{align}$ $\huge \begin{align} m &= \rho V = \rho S ct \end{align}$ Where $\rho$ represents [[Density]], $S$ is the cross sectional [[Area]], $c$ is the [[Wave Speed]], and $t$ represents [[Time Domain|time]]. $\huge \boxed{E = \frac{1}{2}\rho Sct \omega^{2}A^{2}} $
