Where will light rays meet? Here F1 and F2 represent primary focus and secondary focus of the lens respectively.
F1
Rays coming from an infinite source on passing through a convex lens converge at the real focus of the lens. The primary focal point (F1) of a lens is also called the Object-Space Focus. Here F1 acts as real focus as parallel rays coming from real object. Parallel rays coming from virtual object meets at F2.
