An object is placed at the following distances from a concave mirror of focal length 16 cm, turn by turn:
(a) 36 cm
(b) 32 cm
(c) 21 cm
(d) 9 cm
Which position of the object will produce:
(i) a magnified real image?
(ii) a magnified virtual image?
(iii) a diminished real image?
(iv) an image of same size as the object?
(i) A magnified real image - 21 cm - When the object is placed between focus and centre of curvature.
(ii) A magnified virtual image - 9 cm -When the object is placed within its focus.
(iii) A diminished real image - 36 cm -When the object is placed beyond the centre of curvature.
(iv) An image of same size as the object - 32 cm -When the object is at the centre of curvature.
