A symmetrical biconcave thin lens is cut into two identical halves, and they are placed as shown in the figure -
We are required to find the total number of images of the object, formed in the above particular case.
According to me, only 2 images should be formed - one after refraction through both lenses, and one after refraction through first lens (or second) only. However, the answer given says that a total of three images are formed, and I'm not able to locate where and how the third image is formed.
Am I missing something obvious? Please guide me in the right direction, and help me understand the above concept. I'm not able to understand why there should be a third image - only two seem obvious to me.
Thanks a lot.
