Derive speed of sound
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: WebThe speed of sound at 20 degrees Celsius is about 343 meters per second, but the speed of sound at zero degrees Celsius is only about 331 meters per second. …

WebJan 18, 2024 · Since a sound wave is a longitudinal wave, we can use this relation to derive the formula for the speed of sound through a medium. Newton assumed that the propagation of sound through a medium is an … WebDerivation of the Speed of Sound in Air As stated earlier, the speed of sound in a medium depends on the medium and the state of the medium. The derivation of the equation for the speed of sound in air starts with …
WebThe restoring property for sound is the adiabatic bulk modulus of the air, γP A. γP A is like a three dimensional 'spring constant', where P A is the atmospheric pressure and γ is a numerical constant associated with adiabatic (rapid) deformations. So the speed of sound is v = √ (γP A /ρ). WebSound Waves Physics Derivation of speed of sound wave propagation JEE Advanced
