Dear Dorcas,

this is a very interesting statement when standing alone in space.

Please share a little bit more details about your statement.

 Why should the velocity of a material depend on its density at all

and how does your material get the velocity?

What is your material for example and how is the environment configured? etc.

Thanks in advance

I agree with Gerhard ,it is difficult to answer your question since not enough information is provided

I will rephrase thus : "Is the velocity of waves through a material inversely proportional to the density of the material or directly proportional ?"

Dear Dorcas,

ah, now you are writing about waves not on matter any more. Thanks.

According to the Newton-Laplace equation for example the speed of sound in matter is inverse proportional to the root of its density.

Please have a look at the links.

Thanks Gerhard, your response is highly valued. From the explanation it showed I was right.

Cheers!

But Dorcas,

please pay attention:

The speed  v of sound is inverse proportional to the square root of the density rho :

v ~ 1/(rho)1/2 and not v~ 1/ rho   as one might expect from the content of your question.

Yes I understand that.

I am actually stating the proportionality relationship, not minding the exact equation formular.

Thanks.
