Question

The speed of sound V in a medium is directly proportional to wavelength,the young modulus and the density of the medium. Use the method of base units to find the formula for the speed of sound​

Answer 1

A basic and most important concept to find velocity of sound is ...

v =$\sf\sqrt{\frac{\textbf{elastic property}}{\textbf{inertial property}}}$

in case of fluid, elastic property is measured with help of bulk modulus and inertial property is measured with help of density.

and density is

this is the required expression of velocity of sound, bulk modulus and density of fluid.

Answer 2

A basic and most important concept to find velocity of sound is ...

v =\sf\sqrt{\frac{\textbf{elastic property}}{\textbf{inertial property}}}

inertial property

elastic property

in case of fluid, elastic property is measured with help of bulk modulus and inertial property is measured with help of density.

Hope it helps you !!!
