In a portrait Marianne was painting of a friend, she incorporated a lamp with a shade. To show that the lamp was turned on, Marianne painted a reflection of the light on the wall behind the lamp. The reflection of the light on the wall was in the shape of a conic section formed when a plane intersects both nappes of a double-napped cone parallel to the symmetry axis. What conic section was represented on the wall?

Defining - A conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic sections are the hyperbola, the parabola, and the ellipse. The circle is type of ellipse, and is sometimes considered to be a fourth type of conic section.
