1) A candle is placed in front of a convex lens of focal length 20cm.Complete the following table which describes the nature and size of the image formed by the lens.
Dear student,
(a) When the object is at 50 cm it is beyond 2 F, so the image formed is real, inverted and diminished in size.
(b) When the object is at 40 cm it is at 2 F, so the image formed real, inverted and of the same size as that of the object.
(c)When the object is at 15 cm it is between the pole and the focus and the image formed will be, virtual, upright and enlarged.
(d) When the object at 32 cm it is between F and 2 F, so the image formed will be, real, inverted and greater than the size of the object or enlarged.
