    Hello there,

    My question is how does the wavelength of spherical longitudinal waves (compression waves) change with the radius (while moving away from the origin). And also how do the overall properties of the waves change. We consider that there is no gravity or any other external force acting upon the medium. Also, the medium is composed of linked particles, like water, and not separated, like air, but is there a difference?
    I am particularly interested if there is a case in which the wavelength increases.
    (An explanation in words rather than math would be much appreciated)

    Thank you in advance!

    In this thread the balance of opinion was that the frequency decreased very slightly.
    Why does sound wave frequency not decrease over distance?
    I haven't been able to find a reason though as to why that should be the case, so I'm no buying it.
