1. The image in (concave, convex) lens is either inverted or upright image depends
on the distance of the object.
2. In the convex lens, the image is upright when the object is located between (V to
F, F to 2F).
3. When the image is located at 2F in a convex lens it (reduces, remain the same) the
size.
4. If the image in the convex lens is smaller than the object, then the object is located
(beyond 2F, between F and 2F).
5. All image formed in the concave lens is upright. (true, false).
6. In a concave lens, the image is always (smaller, bigger) than the object.
7. In a (concave, convex) lens, the image will depend on the location of the object to
the lens.
8. The image is always located between V and F in a concave lens then the object is
located at (fix, any) distance/s.
9. When the image in the convex lens is virtual, upright and bigger than the object,
the object is located between (2F and F, V and F, V and 2F).
10. The distance of the vertex to focus is the same with the distance between focus
to second foucus. ( True, False)​
