When Superposition Rule Doesn’t Work?
Superposition is such an obvious rule in Physics that it’s worth telling when it doesn’t work. The rule breaks, when equatation of a wave is not longer linear. It happens when the altitudes are big enough to make the Hook’s Law fail ( ). Example: Shock waves after explosions which characteristic differs from a normal sound wave. Their propagation is meant by squared equatation.
