What is the speed fo sound?

Answer 1

Speed of sound in air, at standard temperature, is about 330 meters/second, but the speed of sound varies a lot among different substances.
Sound waves travel at 20°C (68°F) with the speed of sound c = 343 m/s or 1125.33 ft/s.
Sound travels at 726 mph in air. It travels faster when the air is denser, which is why there is no sound in space. It travels fastest in metals and similarly dense objects. It can reach around 1500 mph.
The speed of sound is 330 m/s. The speed of light is 3*108 m/s. Light propagates faster than sound waves.

Answer 2

The speed of sound varies depending on altitude, temperature and the medium through which it travels. For example, at sea level in a standard atmosphere, at a temperature of 59-degrees Fahrenheit (15 Celsius), sound travels 761 miles per hour (1,225 km/p/h). At a temperature of 32-degrees Fahrenheit (0 Celsius) the speed of sound drops to 742 mph (1,194 km/p/h). In altitudes above sea level the speed of sound is again different and will vary depending on prevailing factors.

Answer 3

Depends on what you compare it to. To a human on foot - sure. To a human in a car sure. To a bullet out of a rifle - not that much. To a fighter aircraft - not particularly. To a rocket capable of reaching orbit - not at all.

Answer 4

The speed of light is determined by the medium it is propagating in, as well as other factors such as humidity and temperature. The speed of sound in helium at 0 degrees Celsius is approximately 972 metres per second.

Answer 5

It depends on what it is travelling in e.g air or water, but in air it is 1,236 kilometers per hour or 768 mph

Answer 6

In dry air at a temperature of 20 degrees Celsius, the speed of sound is 343 meters per second. However, sound travels faster in liquids and non-porous solids than it does in air.

Answer 7

Speed of sound in air is c ≈ 331 + 0.6 × T.

T = Temperature in °C.

Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

Answer 8

The speed of sound in fresh water at 20 oC is 1482m/s. (Hypertextbook)
