In order to obtain a magnification of, −0.6 (minus 0.6) with a concave mirror, the object must be placed
(a) at the focus
(b) between pole and focus
(c) between focus and centre of curvature
(d) beyond the centre of curvature
Answers
The object should be placed beyond the center of curvature to obtain a magnification of -0.6 with a concave mirror.
Explanation:
We should place the object beyond the center of curvature in order to obtain a magnification of minus 0.6 (-0.6), when the concave mirror is used since a weakened image is produced at this point. When the sign is negative, it shows that the image is inverted and real.

Answer:
Answer: To obtain a magnification of -0.6 with a concave mirror, the object should be placed beyond the centre of curvature (that is 0.3). Explanation: In a 'concave mirror', the magnification is the ratio of the "height of the object" or "image distance" to the "height of the object" or "object distance”.
