Concept

Problem: An amoeba is 0.305 cm away from the 0.300 cm- focal length objective lens of a microscope.(a) An eyepiece with a 2.00-cm focal length is placed 20.0 cm from the objective. Where is the final image?(b) What angular magnification is produced by the eyepiece?(c) Suppose the objective lens of the microscope had a magnification of - 60 before placing the eyepiece from the objective, what is the overall magnification?

Lens equation:

1so+1si=1f

Magnification:

m=hiho=-siso

(a)

The object distance so from the objective lens will be:

soe = 20 - 18.30 = 1.7 cm
