Unformatted text preview: seen, and object and image are a focal length away. Experiment 2: Focal Length Lens Formula: Use the ground glass to get an image of the object. Calculate the focal length from the object and image distances. Experiment 3: Focal Length of Diverging Lenses: Combine the diverging lens with a known convergence lens. Measure the focal length. Experiment 4: Simple Magnifier Loupe: Use the object and ground glass to observe the magnifying properties and to measure the maximum magnification. View a piece of ruler with the same lens and estimate the magnification. Experiment 5: Astronomical Telescope: Construct the telescope using the 25 cm lens for the objective and the 5 cm lens for the eyepiece. View a piece of ruler and estimate the magnification. Then view a bright object across the room. Experiment 6: The compound microscope: Make a microscope using lenses #6 and #7. View the ruler attached to the object and estimate the magnification....
