Want this question answered?
because in the fingerprint pattern the delta and core is considered the focal points ohhh.... diba?
I am so happy that you all found a facebook for my daughter
In art a composition's focal point is actually called the focal point. There may be multiple focal points, in which case the main one is the focal point and the others are secondary focal points. You can recognize the focal point because it is somehow set apart from the rest of the composition.
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.

A parfocal lens is a lens that stays in focus when magnification/focal length is changed. There is inevitably some amount of focus error, but small enough to be considered insignificant.
the prefix for focal is infocals
focal length of the lens

It does not. For an explanation of "focal plane" see the question What is the focal plane?
