Acoustic trapping is a technique that uses sound waves to manipulate and hold particles or small objects in a stable position without physical contact. This method leverages the pressure nodes and antinodes created by standing waves to exert forces on the objects, making it useful in fields like biophysics and materials science for non-invasive manipulation of delicate samples.

Acoustic Trapping

Sound waves are longitudinal waves that travel through a medium by compressing and rarefying particles, allowing us to perceive sound. They are characterized by properties such as frequency, wavelength, amplitude, and speed, which determine the pitch, loudness, and timbre of the sound we hear.

Physical contact is a fundamental aspect of human interaction that can convey emotions, establish connections, and communicate intentions without words. It plays a crucial role in social bonding, emotional well-being, and even in the development of trust and empathy between individuals.

Antinodes

Standing waves are a pattern of vibration that simulates a wave standing still, formed by the interference of two waves traveling in opposite directions with the same frequency and amplitude. They are characterized by nodes, where there is no movement, and antinodes, where the amplitude is greatest, and are fundamental in understanding resonance and harmonics in various physical systems.
