An object is placed beyond 2F from a convex lens. Image position is:
AAt the optical centre
BAt F on the same side
CBeyond 2F on the other side
DBetween F and 2F on the other side
Answer & Solution
Correct answer: D. Between F and 2F on the other side
1. The standard ray diagram for object beyond 2F gives a smaller real inverted image.
2. The image lies between F and 2F on the opposite side of the lens.
3. The image is reduced in size compared with the object.
4. So image position is between F and 2F on the other side.
