A concave lens always forms an image that is:
AVirtual and erect and diminished
BReal and inverted under typical conditions
CReal and magnified
DVirtual and inverted
Answer & Solution
Correct answer: A. Virtual and erect and diminished
1. A concave lens diverges incident rays.
2. Diverging rays cannot meet, so the image is virtual.
3. The virtual image is upright (erect) and smaller than the object.
4. So a concave lens always gives a virtual, erect, diminished image.
