SUMMARY
The velocity of sound in a medium is determined by the equation v = √(elastic constant/density), as established by Newton. This indicates that an increase in density results in a decrease in sound velocity; however, this relationship is nuanced. In solids like iron, which have high density, the velocity of sound is also high at 5221 m/s due to the significant elastic constant. The critical factor is the ratio of bulk modulus to density, which influences sound propagation, as increased density alone adds inertia, making particle movement more challenging.
