Rayleigh scatterer

Rayleigh scatterer

[rā′lē]
Etymology: John W.S. Rayleigh, English physicist, 1842-1919
reflecting objects whose dimensions are much smaller than the ultrasonic wavelength. The scattered intensity from a volume of Rayleigh scatterers increases rapidly with increasing frequency, being related to frequency raised to the fourth power.
