Question

When was the wave equation discovered?

Answer 1

1. In the year 1746, the one-dimensional wave equation was discovered by D'Alembert.
2. After ten years, the three-dimensional wave equation was discovered by Euler.
3. It is a second-order partial differential equation, which describes the standing wave nature.
4. The wave equation is written as: $v=\lambda f$ where, $v=velocity,\lambda =wavelength,andf=frequency$
