A convex lens is used to form an image of an object. When the object is placed at a distance greater than twice of the focal length (2f) of the lens, what is the nature of the image formed?
Real, inverted and diminished
For a convex lens, when the object is placed beyond twice the focal length (u > 2f), the image is formed between f and 2f on the other side of the lens.
Using the ray diagram or the lens formula 1/v − 1/u = 1/f, this image is real (rays actually meet), inverted (turned upside down relative to the object) and diminished (smaller than the object). It cannot be virtual/upright, same size, or magnified for that object position.
Hence, the answer is Real, inverted and diminished.
