Question

When you use a converging lens as a magnifying glass, the object must be placed____________

Answer 1

To use a converging lens as a magnifying glass, place the object closer to the lens than its focal length, creating a larger, virtual, and upright image.

Step-by-step explanation:

When you use a converging lens as a magnifying glass, the object must be placed closer to the lens than its focal length. This creates a virtual, upright, and magnified image of the object, known as a case 2 image. Using a convex lens as a magnifier takes advantage of this phenomenon; as the object is brought closer to the lens, the magnification increases. Once the object is within the focal length, the image will appear larger than the object itself, making the lens an effective tool for magnification.
