Why is the speed of sound more in steel than in water or air?
Speed of sound in a medium is given by, v = √(E/ρ)
E = Young’s modulus for steel
E = Bulk modulus for liquid
E = Adiabatic stress for gas
ρ = Density of the medium.
Since, E of steel is very large compared to air or water, so, the speed of sound in steel is very large.
