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 ...

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 ...

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 ...

Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) and at Florida International University report in the journal Science their insights on the emerging field ...

Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can ...

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

Sound doesn't just enter your ears – it may actually talk to your cells. New research out of Kyoto University shows that ...

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.

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens.
