Answer:
The position of the image = 7.2 cm.
Explanation:
Given:
A Converging lens:
Object distance = 12 cm = -12 cm (sign convention)
Focal length = 18 cm
We have to find the position of the image.
Let the position of the image be .
Sign convention:
The focal length of converging (convex) lens is always positive,while object distance is negative.
Using lens formula:
⇒
