A compound microscope uses an objective of focal length 0.8cm and an eyepiece of focal length 2.0cm. An object is placed 1.0cm in front of the objective. The eyepiece is adjusted so that the final image is formed at the near point (25cm).
(i) Determine the separation between the two lenses required for clear focus.
(ii) Find the magnitude of the overall magnification produced.
a. (i) Lens separation
b. (ii) Overall magnification
