    A microscope has an objective lens with a focal length of 10.0 mm . A small object is placed 0.90 mm beyond the focal point of the objective lens. If an eyepiece with a focal length of 2.5 cm is used, with a final image at infinity, what will be the overall angular magnification of the object? Express your answer using two significant figures.

    An objective lens has a focal length of 1.5 cm and the object is positioned 1.7 cm(do) from the objective lens, what is the distance between the objective lens and the image (di) produced by the objective lens? What is the magnification produced by the objective lens? The real image formed by the objective lens then becomes the "object" for the eyepiece lens. If the objective and eyepiece lenses are 15.0 cm apart, what is the distance between the "object"...
