Answer:

It depends on the elasticity of the medium

Step-by-step explanation:

If the travelling wave is a longitudinal wave then the speed of the wave is given by the formula

$v = \sqrt{(E)/(\rho)}$

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

E = Y (Young's Modulus)

and for liquids and gases it is given as

E = B (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
