A concave lens always forms what kind of image for a real object, regardless of the object's position?
AA virtual, erect and diminished image
BA virtual, inverted and magnified image
CA real, inverted and magnified image
DA real, erect and same-size image
Answer & Solution
Correct answer: A. A virtual, erect and diminished image
1. A concave lens is a diverging lens; refracted rays appear to spread from a point on the object side.
2. For any real object the image lies between the optical centre and focus.
3. That image is always virtual, erect and smaller than the object.
4. Concave lenses cannot form real images of a real object, ruling out those options.
