Velocity formula sound. Find the wavelength of a sound wave that has a frequency of 200 cycles per second the low end of human hearing. The velocity of sound is a vector u whose magnitude u is the speed of sound u and whose direction is normal to the surface of constant phase. Where v velocity of the wave f frequency of the wave λ wavelength.

K Bulk Modulus of Elasticity Pa psi ρ density kgm3 lbft3 This equation is valid for liquids solids and gases. C V heat capacity at constant volume. Experimentally it has been found that the velocity of sound in air is 332 ms.
K T isothermal compressibility. L cavity length. The wave velocity v 340 ms and the frequency f 200 cycless.
For air at sea level the speed of sound is given by. In the equation V dt V is the velocity d is the distance and t is the time. R position vector.
Examples of sound velocity A general expression for the velocity of sound in gases is given by Equation 83 where γ is the ratio of the specific heats of the gas 1414 in the case of air P is the pressure and ρ is the density of the gas. K wave vector. A special formula for the speed of sound in a liquid is o c BT ρ γ 7 where γ is the ratio of specific heats BT is the isothermal bulk modulus ρ o is the equilibrium mass density.
