An optical cavity, also known as a resonating cavity or optical resonator, is a mirror or other optical element arrangement that forms a cavity resonator…

Acoustic impedance and specific acoustic impedance are measures of a system’s resistance to acoustic flow caused by an acoustic pressure applied to the system. The…

Cavity optomechanics is a branch of physics that focuses on the interaction between light and mechanical objects on low-energy scales. It is a field of…

The acoustic contrast factor is a number used to describe the relationship between the densities and the sound velocities (or, equivalently because of the form…

Scientists from KAUST have shown how small semiconductor lasers may be easily modified to make them more useful for lighting and holography. The study has…

Radiation pressure (also known as light pressure) is the mechanical pressure exerted on any surface as a result of the object’s momentum exchange with the…

Quantum interference refers to the phenomenon in quantum mechanics where the wave nature of particles leads to constructive or destructive interference. It is a fundamental…

Acoustic levitation is a fascinating phenomenon that involves suspending and manipulating objects in mid-air using sound waves. It is a technique for suspending matter in…
