Answer 2

Explanation:

Image formation by Convex Lens

Object location Image location Image nature Image size

Infinity At F2 Real and Inverted Diminished

Beyond 2 F1 Between 2F2 and F2 Real and Inverted Diminished

Between 2F1 and F1 Beyond 2F2 Real and Inverted Enlarged

At F1 At infinity Real and Inverted Enlarged

At 2 F1 At 2F2 Real and Inverted Same size

Between F1 and 0 On the same side as the object Virtual and Erect Enlarged
