Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

The film "LearningAboutSound" explores the science of sound, detailing how vibrations create sound waves that travel through different mediums like air, water, and solids. It explains key concepts ...

Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can greatly affect how sound waves travel from one point to another.

Yet water doesn’t mute sound, but amplifies it. Sound waves travel 4.3 times faster underwater than they do in the air and they retain their energy for much longer.

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 ...

Since sound is made up of mechanical waves that travel through substances like air, water or tissue, the researchers designed a system to "bathe cultured cells in acoustic waves".
