Experiment _ Introductory Optics System Image Formation from Spherical Mirrors I - EQUIPMENT NEEDED: -Optics Bench, Light Source -50 mm F. L. Spherical Mirror -Crossed Arrow Target. -Component Holder (3) -Viewing Screen Introduction Figure 12.1 Equipment Setup If you cut a thin strip along any diameter of a spherical mirror, the result is a close approximation to a thin cylindrical mirror. With this in mind, it's not surprising that images fonned with spherical mirrors exhibit many of the same properties as those formed with cylindrical mirrors. In this experiment, you will investigate some of these properties. Procedure Focal Length Set up the equipment as shown in Figure 12.1, with the concave side of the mirror facing the Light Source. The Viewing Screen should cover only half the hole in the Component Holder so that light from the filament reaches the mirror. To verify the focal length of the mirror, position the mirror on the optical bench as far from the Crossed Arrow Target as possible. Vary the position of the Viewing Screen to find where the
