alleryImage formed by a convex lens with object at infinity is:
AAt centre, virtual, large
BAt focus, real, point-sized
CAt 2F, magnified
DOn the same side, erect
Answer & Solution
Correct answer: B. At focus, real, point-sized
1. Parallel rays from infinity arrive at the lens.
2. They converge at the principal focus F on the other side.
3. The image is real and reduced to nearly a point.
4. So image is at F, real, very small.
