## 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?

It is the k-ellipse but not with 3 points - with 3 circles!

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.
