A convex lens of small focal length used as a magnifying glass (simple microscope) forms an image with which set of characteristics?
AReal, inverted and diminished
BVirtual, erect and magnified
CReal, erect and magnified
DVirtual, inverted and diminished
Answer & Solution
Correct answer: B. Virtual, erect and magnified
1. A simple microscope is a short-focal-length convex lens with the object inside its focus.
2. In this position the lens forms a virtual, erect and enlarged image.
3. This is why it magnifies for watch repair and gem testing; a real inverted image would not serve that purpose.
