What is the wavelength of a 2,000-kHz sound wave (a) in air, (B) in helium, and (c) in water?© BrainMass Inc. brainmass.com July 23, 2018, 12:21 am ad1c9bdddf
Please see the attached file.
a) Velocity of sound in a liquid is given by the equation : V = √K/ρ ........(1)
where K = Bulk modulus of elasticity of the liquid and ρ is the density.
b) Velocity of sound in a gas is given by the equation : V = √γP/ρ .......(2)
where P = Pressure,
ρ = Density
γ = Ratio of the specific heats of the gas at constant pressure and constant volume ...
The problem has been solved using the relation between velocity, frequency and wave length.
