Here are two ray diagrams for compound microscope, the first one proposed by the book, and the second one recommended by the teacher:
In the first image, the light rays form a real image A'B', which becomes the virtual object for the eyepiece. See, the original rays are carried forward to the eyepiece, which then form a virtual image, A"B".
In the second image, when the real image A'B' is formed, new rays start from it, and end up forming the virtual image A''B".
I feel the second one is wrong, because new rays cannot start from a real image, but the original rays should go forth and get refracted again to form the virtual image.
What is your opinion? Which diagram is correct?
