Describe with the help of a ray-diagram, the size, nature and position of the image formed by a convex lens when an object is placed beyond 2f in front of the lens.

Q. An object is placed beyond twice the focal length of a convex lens. Find the position nature and size of the image with the help of a ray diagram.

Q. Draw a diagram to represent the nature, position and relative size of the image formed by a i) convex lens for the object placed at $2F$ ii) concave lens for the object placed between $F$ and $2F$.

Q. (a) For which position of an object, a real, diminished image is formed by a convex lens?
(b) Two convex lenses A and B have focal lengths of 2.5 cm and 12.0 cm, respectively. Which lens has a greater power?
​(c) Describe with the help of a labelled ray-diagram, the formation of image when an object is placed in the front of a convex lens between focus and optical centre. State any two characteristics of the image formed.

Q. A miniature sized candle is placed beyond F in front of a convex lens A. Complete the ray diagram for the given setup of lenses and find the nature of the final image formed.​
