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 ...

Sound Waves in Air (1961)
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 have reviewed metamaterials to emulate Schrödinger dynamics, bridging classical wave physics and quantum ...
Underwater waves could also be used to reduce the risks of tsunamis and to improve their early warning systems.
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 ...
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.
A new paper explains how signals oscillating at complex-valued frequencies could transform sensing, imaging, and ...
Researchers manipulated water waves to move ping pong balls with a level of precision that seems straight out of a sci-fi movie.
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.
