Yale scientists have shown how to enhance the lifetime of sound waves traveling through glass — the material at the heart of fiber optic technologies. The discovery will be described in the January ...

We learn a lot about our surroundings thanks to sound. But... what is it exactly? In this episode of Crash Course Physics, Shini goes over some of the basics (and some of the not so basics) of the ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Sound vibrations leave the singer's mouth. The higher the pitch of the sound, the higher the frequency, or number of vibrations in a given amount of time. The sound enters the microphone, where it is ...

Making waves: Amgad Rezk has created a new type of sound. (Courtesy: RMIT Univeristy) A new class of sound wave that can dramatically improve the delivery of inhaled drugs and vaccines has been ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

For the triangle, researchers captured proof that resonance occurs even with the notched, open corner, and it may occur in other instrument shapes as well. WASHINGTON, May 6, 2025 – The triangle is a ...
