Question

Speed of sound waves in a 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

Answer: (A)

Directly proportional to the square root of bulk modulus of the medium

Answer 2

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.
