A convex lens forms a real image when the object is placed:
AAt the focal point F
BBetween F and the lens
CBeyond the focal point F
DAt the optical centre
Answer & Solution
Correct answer: C. Beyond the focal point F
1. For a convex lens, an object beyond F gives a real, inverted image on the opposite side.
2. Between F and the lens, the lens acts as a magnifier producing a virtual erect image.
3. At F, the image is at infinity.
