Some may already be familiar with the sonic boom that accompanies a break to the sound barrier, but when and why would ...

The speed of sound is a term used to describe the speed of sound waves passing through an elastic medium. The speed varies with the medium employed (for example, sound waves move faster through ...

The respective speeds of sound and light are oft-discussed and researched, and we seem to have a pretty good idea of what speeds each can reach. The speed of light is 299,792,458 meters per second ...

Scientists from CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to ...

Strong jet streams across the Atlantic are seeing passenger airplanes knock more than an hour off their flight times, as they hit speeds of 761 mph – the speed of sound. However, they’re not ...

Click to see a step-by-step guide to measuring the speed of sound. STEP 1 - MEASURE DISTANCE: Pick two points in the area that are at least 150 m apart, but within sight of each other.

And on Earth, the speed of sound varies depending on the temperature of the air an aircraft is traveling through. Breaking the so-called sound barrier in 1947 made Chuck Yeager famous.

Strong jet streams across the Atlantic are seeing passenger airplanes knock more than an hour off their flight times, as they hit speeds of 761 mph – the speed of sound. However, they’re not ...

Strong jet streams across the Atlantic are seeing passenger airplanes knock more than an hour off their flight times, as they hit speeds of 761 mph – the speed of sound. However, they’re not ...

High temperatures aren’t the only challenge to high-speed travel. In some cases, the boundary layer doesn’t transition evenly, which means that one half of the vehicle could be impacted by the smooth, ...

Hypersonic weapons, which fly at speeds in excess of Mach 5, or five times the speed of sound, could pose crucial challenges to missile-defense systems because of their speed and maneuverability.
