A compound microscope consists of an objective lens of focal length and an eyepiece of focal length separated by a distance of . How far from the objective should an object be placed in order to obtain the final image at:
(a) the least distance of distinct vision , and
(b) at infinity? What is the magnifying power of the microscope in each case?

(b) A virtual image, we always say, cannot be caught on a screen. Yet when we see a virtual image, we are obviously bringing it on to the screen (i.e., the retina) of our eye. Is there a contradiction?
(c) A diver under water, looks obliquely at a fisherman standing on the bank of a lake. Would the fisherman look taller or shorter to the diver than what he actually is?
(d) Does the apparent depth of a tank of water change if viewed obliquely? If so, does the apparent depth increase or decrease?
(e) The refractive index of diamond is much greater than that of ordinary glass. Is this fact of some use to a diamond cutter?
