speed of sound
varies depending on the temperature, pressure, and density of the medium through which the sound waves travel. For dry air at sea level at 68° F, the speed of sound is 767 miles per hour, or 1235 km/h
The speed of sound is the distance travelled per unit time by a sound wave as it
propagates ..... on the assumption that the wavelength of the sound in the gas is
much longer than the average mean f...
This calculation is usually accurate enough for dry air, but for great precision one
must examine the more general relationship for sound speed in gases.
The speed of sound in an ideal gas is given by the relationship ... For air, the
adiabatic constant γ = 1.4 and the average molecular mass for dry air is 28.95 ...
v is the speed of sound and T is the temperature of the air. One thing to keep in
mind is that this formula finds the average speed of sound for any given ...
For example the average speed of sound in air is 340 m/s but in water almost 5
times, 1498 m/s. See the chart for sound waves in other mediums. (What is a ...
The ideal gas model predicts that the speed of sound in a pure gas will be ...
