Question

Speed of sound waves in fluid is

• A. directly proportional to the square root of bulk modulus of the medium.
• B. inversely proportional to the bulk modulus of the medium.
• C. directly proportional to the density of the medium.
• D. inversely proportional to the density of the medium.

Answer 1

The correct option is A directly proportional to the square root of bulk modulus of the medium.

Speed of sound wave in a fluid is
$V=\sqrt{\frac{B}{\rho }}$
where $B$ is the bulk modulus and $\rho$ is the density of the medium.
