Converging Lens Image Formation

Images are formed at locations where any observer is sighting as they view the image of the object through the lens. So if the path of several light rays through a lens is traced, each of these light rays will intersect at a point upon refraction through the lens.

Exercise 1(a) The object is u = 6cm away from a convex lens of focal length f = 2 cm. The image position can be found from the lens equation 1 6 + 1 v = 1 2 , ∴ 1 v = 1 2 − 1 6 = 3 6 − 1 6 = 1 3 . This implies that v = 3cm. The image is real and inverted.
