Rayleigh principle
WebMar 2, 2024 · Along with his other concerns, Rayleigh turned his attention to the physics of acoustics. He published his Theory of Sound in 1877/78. Building on the work of Helmholtz, published in German 15 years earlier, Rayleigh defined the principles of the propagation, scattering and diffraction of sound. This work laid the foundation for the practical ... WebBook Synopsis Lord Rayleigh--the Man and His Work by : Robert Bruce Lindsay.
