DURHAM, N.C. -- Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The ...

Typically, when a soundwave strikes a surface, it reflects back at the same fundamental frequency with a different amplitude. A new model shows that when a sound wave hits a nonlinear elastic ...

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, beams ...

Everything we see is due to visible light, the very narrow spectrum of electromagnetic waves that our eyes can detect. Since it's difficult to visualize the wave properties of light, however, let's ...

Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time ...

Radio waves from our galaxy, the Milky Way, reflecting off the surface of the Moon and observed by the Murchison Widefield Array radio telescope located in outback Western Australia. Disclaimer: AAAS ...

LOUISVILLE, Ky. (WAVE) - The sun is always shining bright, regardless if clouds obstruct our view or not. The Earth’s surface sometimes absorbs sunlight, while other times it reflects it. The National ...

We saw earlier that when sound waves come from correlated sources then their pressure and associated velocity components simply add. This meant that the pressure amplitude could vary between zero and ...
