Answer:
air water iron helium
v(m/s) 280 2200 17780 39682
Explanation:
The speed of a wave depends on the physical properties of the medium where it travels, in the case of a longitudinal wave such as sound, it depends on the resistance to deformation (volume modulus and the density of the medium
v = [tex]\sqrt{ \frac{B}{ \rho } }[/tex]
in the mentioned materials they are constant
