A coordinate axis as shown below is kept in front of a converging lens at a distance 2f from it where f is the focal length of the lens. What is the approximate shape of the image as seen by an observer on the other side of the lens at a distance 3f from it. Assume that x-axis is the principal axis of the lens.
Options:
Answer:
A
Solution:
The object is at 2f, so its image is real and inverted; viewed by an observer on the other side, the y and z axes both appear flipped while x remains along the principal axis. Hence (A).
