Answer:
Position of image: Behind the mirror.
Nature of image: Virtual, erect and diminished.
Explanation:
Draw the ray diagram in each case to show the position and nature of the image formed when the object is placed:
In front of a convex mirror.
Answer:
(i) (Refer Fig.1) Nature of image: Real, inverted and same size image is formed at the centre of curvature.
(ii) (Refer Fig. 2) Nature of image: Virtual, enlarged and erect image is formed behind the mirror.
(iii) (Refer Fig. 3) Nature of image: Virtual, erect and diminished, image is formed behind the mirror.
(iv) (Refer Fig. 4) Nature of image: Real, inverted and size to size, image is formed at 2F on the other side of lens.
(v) (Refer Fig. 5) Nature of image: Virtual, erect and diminished image is formed between O and F on the same side of object.
