Answer:

When ultrasonic waves is passing through the liquid , the density of the liquid varies layer by layer due to variation in pressure and hence liquid will acts as Diffraction Grating,so called as Acoustic Grating.

Answer:

Diffraction grating :

A diffraction grating is an optical element that separates (disperses) light that is made up of several different wavelengths (e.g., white light) into light components by wavelength.

A grating with a large number of equally spaced parallel slits is the simplest type of grating.

Acoustic grating :

When ultrasonic vibrations pass through a liquid, the density of the liquid fluctuates layer by layer due to pressure variations, and the liquid acts as a diffraction grating, which is known as an acoustic grating.
