An object is kept at a distance of (i) 2x (ii) (3/2)x from a convace lens having a focal length of magnitude x. Draw ray diagrams showing the formation of image in the two cases.

What is/are the point(s) of similarity/dissimilarity between the images formed in the two cases?

Expert Answer:

The required ray diagrams for the two cases are as shown below:


(i) The image formed is virtual, erect and diminished.

(ii) The image is formed between the optical centre and the focus of the lens.


(i) The image is formed nearer to the lens in the second case.

(ii) The image formed in the second case, is smaller in size than the image formed in the first case.
