IMAGE DISTANCE IS -48 cm.
Given:
- Object distance = 12 cm
- Real image is 4 times object
To find:
- Image distance ?
Calculation:
We know that :
- When the image is real, it is inverted. Hence the magnification sign will be negative.
Now, we can say:
- "v" is image distance and "u" is object distance.
So, image distance is -48 cm.
