Final answer:
The image formed when looking through a converging lens with an object placed at 12.0 cm will be real, inverted, and magnified since the object is located between the focal length and twice the focal length from the lens.
Step-by-step explanation:
When an observer looks through a converging lens with a focal length of 8.0 cm at an object that is 12.0 cm from the lens, the image formed will have specific characteristics. Since the object is farther from the lens than the focal length but closer than twice the focal length, the image will be inverted(turned upside down) and enlarged(larger than the object).
This is based on the understanding that for a converging lens, any object placed between one focal length and twice the focal length from the lens will produce a real, inverted, and magnified image. However, since the object distance (12 cm) is greater than the focal length (8 cm) but less than twice the focal length (16 cm), the image formed will appear on the same side as the object and be magnified and real.
