alleryStart learning →For a concave mirror, when the object is placed at the centre of curvature, the magnification is
A+1
B-2
C+0.5
D-1
Answer & Solution
Correct answer: D. -1
1. Object at C gives an image at C of the same size, so the magnitude is 1.
2. The image is real and inverted, so the sign is negative.
3. Hence the magnification is -1.
