Acoustic radiation pressure is the apparent pressure difference between the average pressure at a surface moving with the sound displacements (the Lagrangian pressure) and the pressure that would have existed in the fluid of same mean density at rest. Numerous authors make a distinction between the phenomena of Rayleigh radiation pressure and Langevin radiation pressure.
Famous quotes containing the words radiation and/or pressure:
“There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.”
—Camille Paglia (b. 1947)
“I am convinced that our American society will become more and more vulgarized and that it will be fragmentized into contending economic, racial and religious pressure groups lacking in unity and common will, unless we can arrest the disintegration of the family and of community solidarity.”
—Agnes E. Meyer (1887–1970)
