    lol, I thought you are trying to advertise ringtones for mobiles.

    I think it is a simple geometry - think about distances covered by different rays before they interfere.

    Consider how those patterns are typically produced--by putting a convex piece of glass over a flat plate. The curved surface has a spherical symmetry that leads to circular rings.
