The human ear detects sound. Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. These bones transmit most efficiently ...

Researchers have reviewed metamaterials to emulate Schrödinger dynamics, bridging classical wave physics and quantum ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes ...

Phoxonic crystals harness the interaction between light and sound waves through optomechanical coupling. This coupling arises from the fact that light can exert pressure on mechanical structures, ...

A new study shows that sound isn’t just heard by the ears. Sound waves altered gene expression and influenced fat cell ...

Cells are sensitive to many forms of stimuli including light and heat, but little is known about the cellular response to ...

Here we use photonics, or light energy, to produce the sound wave. This approach has multiple advantages, chief of which is that light does not produce the heat in the chip that electronic ...

To achieve this, the researchers used "acoustic metasurfaces" which can precisely manipulate the paths of sound waves as they travel — "similar to how an optical lens bends light," wrote Zhong ...

In conventional light-wave- and sound-wave-based systems such as wireless cell phone technologies, microscopes, speakers and earphones, control over wave phenomena is limited by constraints ...

Different materials and molecules inside the tissue absorb different amounts of the incident light at different wavelengths, creating individual "fingerprints" in the emitted sound waves.

The process is very similar to ultrasound imaging, however the sound waves used are within normal hearing range, and they are used to identify objects rather than internal structures. This ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.
