Speed of longitudinal waves
WebFor helium, γ = 5/3 and the molecular mass is .004 kg/mol, so its speed of sound at the same temperature is. v sound in helium = m/s = ft/s = mi/hr. Doing this calculation for air at 0°C gives v sound = 331.39 m/s and at 1°C gives v sound = 332.00 m/s. This leads to a commonly used approximate formula for the sound speed in air: WebWe can find the speed of sound by looking at the speed of this compressed region as it travels through the medium. In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. We can also watch the speed of sound of a repeating simple harmonic wave.

WebIn the Kundt's tube experiment, longitudinal sound waves are produced in a metal rod, which produces them in an air column. Using the speed of sound in air and the wave relationship, the frequency of the sound and the speed of sound in the rod can be determined. The apparatus consists of a glass tube supported on a metal base as shown in the ... WebIt can be shown that the speed of a longitudinal wave in the bar is given by, The relation between pressure P and volume V is: PV = NkBT. Where N is the number of molecules in volume V, k B is the Boltzmann constant and T the temperature of the gas (in Kelvin).
