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

A concave mirror produces a magnified image in the following cases:

1. When the object is placed in front of the mirror, between its pole (P) and focus (F)

2. When the object is placed in front of the mirror, between the focus(F) and the centre of curvature(C)

The differences between the images are:

Case 1	Case 2
A virtual image is formed behind the mirror	A real image is formed in front of the mirror
The image is erect	The image is inverted

Case 1: (Object between P and F)

Case 2: (Object between F and C)
