Solution to wave equation

    • Does an equation always have a solution?

      An equation does not always have a solution. Sometimes, an equation can have a variable that does not equal the remaining value on the other side. For example, root negative x could never equal a number squared. This equation cannot have a solution because you can't square any number to get a negative solution.

    • What is wave equation in physics?

      The wave equation is an important second-order linear partial differential equation for the description of waves—as they occur in classical physics—such as mechanical waves (e.g. water waves, sound waves and seismic waves) or light waves.

    • What is the universal wave equation?

      The Universal Wave Equation. There is a relationship between frequency (f), speed (v) and wavelength (λ) If the source vibrates faster (greater frequency), the wavelength changes. This relationship is described by the universal wave equation. v = fλ.

      I can conclude that the solution to the wave equation is a sum of standing waves. However, we also know that if the wave equation has no boundary conditions then the solution to the wave equation is a sum of traveling waves. This is still true (recall the reflection principle) if the boundary conditions are imposed.

(ii) Any solution to the wave equation u tt= u xxhas the form u(x;t) = F(x+ t) + G(x t) for appropriate functions F and G. Usually, F(x+ t) is called a traveling wave to the left with speed 1; G(x t) is called a traveling wave to the right with speed 1.
