The compound microscope consists of two converging lenses: the objective and the eyepiece. Suppose the focal length f_1 of the objective is 20 cm, and the focal length f2 of the eyepiece is 20 cm. The separation between the objective and eyepiece is 66 cm. The object is located 30 cm in front of the objective. (These numbers are not realistic for a real microscope.) a. Calculate the location and magnification of the image, and state whether it is a...

In a compound microscope, the objective has a focal length of 0.48 cm, while the eyepiece has a focal length of 1.9 cm. The separation between the objective and the eyepiece is L = 10.0 cm. Another microscope that has the same angular magnification can be constructed by interchanging the two lenses, provided that the distance between the lenses is adjusted to a value L'. Find L'.
