Derivation of the Wave Equation in 1 Dimension. Is this the most important differential equation in classical physics? We derive the classical wave differential equation for a wave on a string.
Some fantastic further videos on the subject:
This video was inspired by Walter Lewin's MIT lecture and here are the consequences of this equation:
