MCQ
Speed of sound waves in a fluid depends upon:
- ADirectty on density of the medium.
- BSquare of Bulk modulus of the medium.
- CInversly on the square root of density.
- ✓Directly on the square root of bulk modulus of the medium.
✓
Answer
Correct option: D.
Directly on the square root of bulk modulus of the medium.
Speed od sound wave in fluid of bulk modules $k$ and density $\rho$ is given by $\text{v}=\sqrt{\frac{\text{k}}{\rho}}$
so $\text{v}=\sqrt{\text{k}} ($if $\rho$ is constant$)$
And $\text{v}=\sqrt{\frac{1}{\rho}} ($if $k$ is constann$)$
so verifies the option $(d)$.
so $\text{v}=\sqrt{\text{k}} ($if $\rho$ is constant$)$
And $\text{v}=\sqrt{\frac{1}{\rho}} ($if $k$ is constann$)$
so verifies the option $(d)$.
