What is this curve?
When we have not a circle but a line we have a parabola!
When we have a circle we have line (r=0), hyperbola and ellipse? Or?

Hi,
It seems the curve resulting from the intersection with a horizontal plane of a wave front that propagates in environments with physical properties different from each other.
