Lord Rayleigh was an English physicist who made major contributions to the studies of acoustics and wave propagation. He studied the ways waves pass through fluids and predicted the existence of surface waves. Surface waves are waves that travel along the boundary between two mediums of different densities. These waves are now known as Rayleigh waves. He also discovered Rayleigh scattering, the scattering of light when it passes through gases.
He was awarded the 1904 Nobel Prize in Physics for his work researching the noble gases and the discovery of argon
