The light intensity distribution in the orders of a diffraction pattern produced by the interaction of progressive ultrasonic surface waves and a monochromatic light beam is calculated. From the diffracted light intensity one can determine the amplitude of the surface wave, and from the spacing of the diffraction orders one obtains the velocity of the surface wave. Author
