Calculate the speed of sound in air based on the ambient temperature.
The speed of sound is the distance traveled per unit of time by a sound wave as it propagates through an elastic medium. In air, it is primarily affected by temperature.
As temperature increases, the kinetic energy of the air molecules increases, allowing them to transmit the pressure wave faster. Contrary to popular belief, air pressure itself does not affect the speed of sound in an ideal gas.
Where:
• v is the speed of sound (m/s)
• T is the temperature in degrees Celsius (°C)
Yes, slightly. Humidity increases the speed of sound because water vapor molecules are lighter than nitrogen and oxygen molecules, making the air less dense.
Mach 1 is the speed of sound. An object traveling at Mach 2 is traveling at twice the speed of sound in its current environment.
At high altitudes, the temperature is much lower. Since sound speed depends on temperature, it is slower in the cold upper atmosphere.
No. Sound is a mechanical wave that requires a medium (like air, water, or metal) to travel. In space, there is no medium, so sound cannot propagate.
