Convex Lenses
(i)When an object is placed at infinity,
Position – at the focus.
Nature – highly diminished and point size.
(ii)Beyond the centre of curvature (C or, 2f)
Position of the image – In between the centre of curvature( C or, 2f) and focus(f)
Nature of image – Real, Inverted , diminished .
(iii) At the centre of curvature [C or, 2f]
Position of the image – at the centre of curvature,
Nature of image – Real, Inverted , Same size .
(iv) In between the centre of curvature(C or 2f ) and focus ( F)
Position of the image -behind the centre of curvature.
Nature of image – Real, Inverted , Magnified (larger than that of the object.
(v) at focus (F)
When an object is placed at the focus,
Position of the image – at infinity.
Nature of image – Real, Inverted, highly Magnified ( much larger than that of the object).
(vi) In between focus(F) and optical centre (O)
When an object is placed in between focus and optical centre,
Position of the image – Same side of the object.
Nature of image – Virtual, erect, highly Magnified ( much larger than that of the object).
