Q:

What is acoustic levitation?

A:

Quick Answer

Acoustic levitation utilizes the properties of sound to lift solids, heavy gases and liquids. It is a scientific phenomenon that levitates and moves objects in mid-air. The principles of acoustic levitation revolve around the relationship between gravity, air and sound.

Full Answer

Gravity is a force that attracts objects to one another. Isaac Newton���s law of universal gravitation states that the larger an object is, the more strongly it attracts other objects and that the closer objects are, the stronger their attraction.

Air is a fluid made of microscopic particles that move in relation to each other.

Sound, the third component of acoustic levitation, is a vibration that travels through a medium, such as a liquid, gas or a solid object. The source of sound stems from a moving or shifting object. Sound travels by reacting with moving molecules around it. Sound could not travel without moving molecules, which is why sound does not exist in a vacuum. Sound is a disturbance in an object that shifts energy from one point to another.

Acoustic levitation utilizes the movement of sound through a medium, typically a gas, to counter the effects of gravity. In theory, acoustic levitation can be used on any object. The most substantial limitation with the science is that the object���s diameter must correspond to roughly half the wavelength of the corresponding sound wave.
