Question

What types of images are formed by a convex lens?

Hint:

Concave lenses, in contrast, always form virtual, erect, and diminished images regardless of object position.

Answer 1

Step 1: Understanding the Concept:
A convex lens is a converging lens that can form different images based on object placement.

Step 2: Detailed Explanation:
A convex lens is versatile.
For most object positions (beyond the focal point), it forms a real and inverted image on the opposite side of the lens.
This real image can be magnified, diminished, or of the same size.
However, if the object is placed very close to the lens (between the optical centre and the principal focus), it forms a virtual, erect, and magnified image on the same side as the object (like a magnifying glass).

Step 3: Final Answer:
It can form both real (inverted) and virtual (erect) images.
