Answer:
It depends on the elasticity of the medium
Explanation:
If the travelling wave is a longitudinal wave then the speed of the wave is given by the formula
[tex]v = \sqrt{\frac{E}{\rho}}[/tex]
now we know that if the elastic property of medium or the density of medium will change then the wave will change its velocity
for solids we can say that
[tex]E = Y[/tex](Young's Modulus)
and for liquids and gases it is given as
[tex]E = B[/tex](Bulk Modulus)
so we can say that velocity of the wave will change due to change in medium because it depends on elasticity of the medium and its density
