Question

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

List two possible ways in which a concave mirror can produce a magnified image of an object placed in front of it. State the difference, if any, between these two images.

Answer 1

(i) The two cases in which a concave mirror produces a magnified image of the given object are when the object is placed between

(a) focus (F) and centre of curvature (C)

(b) focus (F) and pole (P)

(ii) Two differences between these images are that the image formed in case (a) is real and inverted, whereas the image formed in case (b) is virtual and erect.
