Final answer:
The image formed by an object placed 22 cm in front of a diverging lens with a focal length of −11 cm is upright. This is because diverging lenses always create virtual, upright images on the same side as the object, a principle consistent with the negative focal length characteristic of diverging lenses.
Step-by-step explanation:
When dealing with a diverging lens, which by definition has a negative focal length, we can determine the nature of the image formed by using the characteristics of how diverging lenses project images. Since a diverging lens always forms a virtual, upright, and smaller image than the object, when an object is placed in front of a diverging lens, regardless of the object's distance from the lens, we know the image characteristics without further calculations.
For the specific scenario in question, where an object is 22 cm in front of a diverging lens with a focal length of −11 cm, the resulting image will be upright. This is consistent with the optics principles for diverging lenses that state the image formed is always virtual (which means it appears on the same side of the lens as the object) and upright. This is also supported by the negative focal length given, since the focal length for diverging lenses is considered negative by convention.
