Sound spreads both forwards and backward in a space, meaning someone standing nearby can hear you as well as you can hear ...

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.

Gravitational waves are tiny ripples in the fabric of time and space that are created by some of the universe's most powerful events such as colliding black holes.

Sound waves and sea creatures Thousands of marine species from microscopic zooplankton to the largest cetaceans rely on sound for survival and many have evolved unique oral and aural adaptations.

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum.

Sound waves generated from entire fault lines, not single points South of the epicenter, the researchers observed a tilted sound wave pattern that gradually became more vertical over time. When an ...

Identify the features of a sound wave and learn about pitch, frequency, amplitude and loudness in this guide for KS3 Physics students aged 11-14 from BBC Bitesize.

Sound waves can reflect off surfaces. We hear reflected sound waves as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes. Soft ...

The bomb exploded at 8:33 a.m. British time. By 11:44 a.m., the first air wave reached England, having taken 3 hr. 11 min. to travel from Novaya Zemlya at the speed of sound—about 700 m.p.h.

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.

Sound waves (also known as “acoustic phonons”) require particles to travel— whether through air, water, or some other medium —and the vacuum of space doesn’t have nearly enough particles ...
