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" and the objective lens(new do)?

    A Galilean telescope is made with a 40 cm focal length objective lens and a -10 cm focal length eyepiece. As is typical, the separation between the lenses is the sum of the focal lengths, i.e. 30 cm. Usually this telescope would be used to view far distant objects, but suppose the object viewed is only three focal lengths (120 cm) distant from the objective lens (a) On the figure above, sketch the principal rays that determine the size and location...

    Experiment 22: The Compound Microscope f2 Object 2 1 (Objective Lens)d L, (Eyepiece) d#150mm The Compound Microscope A compound microscope uses two lenses to provide greater magnification of near objects than is possible using a single lens as a magnifier. The setup is shown above. The objective lens, L1, functions as a projector. The object is placed just beyond the focal point of L1 so a real, magnified, inverted image is formed. The eyepiece, L2, functions as a magnifier. It...
