Question
The height of a real and inverted image of an object of size 14cm is 21cm. The ratio of the negative of the image distance and the object distance is ____.
- 3/2
- -3/2
- 2/3
- -2/3
Hint:
-3/2
The correct answer is: -3/2
For a real and inverted image, the height of the image is negative and the height of the object is positive. So the magnification of the mirror is negative.
m= height of image/height of object
