Problem
A student wishes to compare the performance of a simple microscope and a compound microscope for the same final image condition (normal adjustment). The simple microscope available has a single lens of focal length 5cm. The compound microscope has an objective of focal length 1cm, an eyepiece of focal length 6cm, and a tube length of 16cm.
(a) Calculate the magnifying power of the simple microscope.
(b) Determine the linear magnification produced by the objective of the compound microscope when the object is placed just beyond its focal point.
(c) Find the overall magnifying power of the compound microscope for normal adjustment.
(d) Using your results, state which instrument gives the greater magnification and by what factor.
