The speed of sound in a medium is determined by its bulk modulus and density. Medium A has a density of 1.5 g/cm³ and a bulk modulus of 2.7 × 10⁹ Pa. Medium B has a density of 1.0 g/cm³ and a bulk modulus of 2.2 × 10⁹ Pa. What is the ratio of the speed of sound in Medium B to the speed of sound in Medium A?
