Speed of sound waves in a fluid depends upon
(a) directly on density of the medium.
(b) square of Bulk modulus of the medium.
(c) inversely on the square root of density.
(d) directly on the square root of bulk modulus of the medium.

The answer is the option (c) and (d) Speed of sound wave in the fluid of bulk modulus K and density \rho is given by

v=\sqrt{\frac{K}{\rho}}

v \propto \sqrt{K} (if \rho is constant)

v\propto\sqrt{\frac{1}{\rho}} (if K is constant)
