Experimentally verified thermodynamic model reduces relative uncertainty of previous model by over one order of magnitude.

The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 ...

Upper limit: a US Navy F/A-18 travelling near the speed of sound in air. The white halo comprises water droplets that have condensed from the air because of the sudden drop in pressure behind the ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make ...

A person fires a starting pistol. A distant observer stood 200 metres away (measured using a 20 m tape measure or trundle wheel) records the time between seeing the flash of light from the starting ...
