Question

Quizplus · Accepted Answer

When an object is placed before a single thin lens, the type of image formed and whether it is enlarged or inverted depends on the distance of the object from the lens and the focal length of the lens. However, in general, real images formed by a lens are usually inverted. Therefore, option C is the best choice. Option A is incorrect because real images can be either enlarged, reduced, or the same size as the object. Option B is incorrect because virtual images are always upright, not inverted. Option D is incorrect because convex lenses can create virtual images when the object is placed closer than the focal length.
