. State two positions in which a concave mirror produces a magnified iinage of a given object. List two differences between the two images


Best Answer

Ans. The two positions are:

(i)  When an object is placed between the pole(p) and focus (j) of a concave mirror, the image formed is larger than the object (or magnified).

(ii)  When an object is placed between the focus (f) and centre  of curvature  (c) of a concave mirror, the image formed is larger than the object.

Difference between the two images

(a)  In case (i), the image   is formed behind the mirror.

In case (i), the image   formed   is virtual and erect.

(b) n case (ii), the image is formed beyond the centre of curvature.

In case (ii), the image formed is real and inverted.
