Given that,
Focal length of a converging lens, f = +25 cm
Size of the object, h = 10 cm
Object distance, u = -30 cm
We need to find the image distance and the size of the image.
Using lens formula, , v is image distance
Magnification,
h' is the size of image
So, the image distance is 150 cm the size of image is 50 cm.
