34.64 A compound microscope has an objective lens with focal length 14.0 mm and an eyepiece with focal length 20.0 mm. The final image is at infinity. The object to be viewed is placed 2.0 mm beyond the focal point of the objective lens. (a) What is the distance between the two lenses? (b) Without making the approximation 5₁- fi, use M myM₂ with my = -si/s₁ to find the overall angular magnification of the micro- scope. (c) What is the percentage difference between your result and the result obtained if the approximation s₁ f₁ is used to find M? 34.64 A compound microscope has an objective lens with focal length 14.0 mm and an eyepiece with focal length 20.0 mm.
