Question

Write characteristics of image formed due to convex lens at various distances.

Answer 1

Position of the object	Position of the image	Relative size of image	Nature of image
1) At infinity	Focal point	Highly diminished	Real & inverted
2) Beyond centre of curvature (2F2)	Between F1 and 2F1	Point size diminished	Real & inverted
3) At the centre of curvature (2F2)	At 2F1	Same size	Real & inverted
4) Between centre of curvature focal point (2F2 and F2)	Beyond centre of curvature	Magnigied	Real & inverted
5) At focal point (F2)	At infinity	Highly magnified	Real & inverted
6) Between focal point and pole F2 and P	On the same side of the lens of the object	Magnified	virtual & erect
