First, we draw a ray parallel to principal axis. So, it passes through focus after refraction. We draw another ray which passes through Optical Center. So, the ray will go through without any deviation. Where both rays meet is point A'. And the image formed is A'B'. This image is formed between F 2 and 2F 2. We can say that.
