(a) Define a simple microscope and a compound microscope.
(b) State any three fundamental differences between these two instruments with respect to:
(i) number of optical elements used,
(ii) sequence in which the images are formed (real/virtual, erect/inverted), and
(iii) typical range of magnifying power obtainable.
(c) Explain, with suitable reasoning, why a compound microscope is able to achieve a much higher overall magnification than a simple microscope even though its eyepiece generally has a larger focal length than the single lens used in a simple microscope.
