Acoustic frequency filters help smartphones separate signals for mobile networks, Wi-Fi, and GPS. Researchers at RPTU Kaiserslautern-Landau now say they have demonstrated a new physical effect that ...

Physicists in Leiden have recreated Thomas Young’s iconic double-slit experiment using gigahertz sound waves on gallium arsenide, revealing both parallels and differences with light. The study found ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water levels create different musical notes and learn about the relationship between mass, vibration ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...
