An optical lens is generally made up of two spherical surfaces and one of those surfaces are bent outwards or convex, which is called a convex lens.
When a needle 10 cm high is placed at 40 cm from a convex lens of focal length 15 cm, then, an image is formed at a distance of 40 cm behind the lens.
The Image so formed is real, inverted and diminished and of 6cm.
