- The speed of a wave or a pulse depends upon the properties of the medium.
- If the medium is uniform or unchanging, then the speed is constant.
\({\rm{v}} = \sqrt {\frac{{{\rm{Elastic\;property}}}}{{{\rm{Inertial\;property}}}}}\) ⇒ \({\rm{v}} = \sqrt {\frac{{\rm{B}}}{{\rm{\rho }}}}\) ;
Where B is the bulk modulus of medium and ρ is the density of the medium.
- Bulk modulus: The relative change in the volume of a body produced by a unit compressive or tensile stress acting uniformly over its surface.
EXPLANATION:
- As the medium is uniform, so density is always constant and bulk modulus for every material is fixed.
- So, the velocity is constant throughout the medium.
