Admin How fast is the speed of sound at ground level?
about 761 mph
If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second.
Does sound travel faster in the ground?
Normally the ground is warmer than the air above, so air temperature decreases with height in the troposphere (up to about 8 miles). Sound travels faster in warmer air, so the sound waves are refracted upward, away from the ground. Other conditions can affect sound propagation near the earth.
What is speed of sound at sea level?
At sea level, the value is right around the 340 m/s mark. If you move up to 120,000 feet, the speed will drop down to around 200 m/s.
Why does the speed of sound at higher altitudes decrease?
The speed varies depending on atmospheric conditions; the most important factor is the temperature. Humidity has little effect on the speed of sound, nor does air pressure by itself. Sound usually travels more slowly with greater altitude, due to reduced temperature.
What is the speed of sound at 38000 feet?
Speed of Sound at a known temperature and density of air
| Altitude | Speed of Sound | |
|---|---|---|
| Feet (ft) | Meter (m) | m/s |
| 30,000 | 9144 | 303.1 |
| 35,000 | 10668 | 295.4 |
| 40,000 | 12192 | 294.9 |
What is the speed of sound in mph at sea level?
On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h). Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air.
Where can you see the speed of sound in real life?
It can be seen today at the Smithsonian Air & Space Museum in Washington, D.C. 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 degrees Celsius) — is 761.2 mph (1,225 km/h).
How fast does sound travel through the atmosphere?
A jet breaking the sound barrier. 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).
What determines the speed of sound at different altitudes?
Speed of Sound at different altitudes (km/h, mph, knots) Speed of Sound (mach) at altitudes depends on temperature not air pressure SPEED OF SOUND AT DIFFERENT ALTITUDES Mach 1.0 is the speed of sound in air, so a plane flying Mach 2.0 is flying twice as fast as the speed of sound.
