Spherical Mirror 1 You wish to create an image that is 10 meters from an object. This image is to be inverted and half the height of the object. You wish to accomplish this using one spherical mirror ▾ Part A What is the focal length f of the mirror that would accomplish this?

An object O is placed at the location shown in front of a concave spherical mirror. Use ray tracing to determine the location and size of the reflected image. As you work, keep in mind the following properties of principal rays: Part A Trace the path of a ray emitted from the tip of the object through the focal point of the mirror and then the reflected ray that results. Start by extending the existing ray emitted from the tip of the object. Then create the reflected ray. 1. A ray parallel to the axis, after reflection, passes through the focal point Fof a concave mirror or appears to come from the (virtual) focal point of a convex mirror. 2. A ray through (or proceeding toward) the focal point Fis reflected parallel to the axis. 3. A ray along the radius through or away from the center of curvature C intersects the surface normally and is reflected back along its original path 4. A ray to the vertex Vis reflected, forming equal angles with the optic axis. Draw the vector for the…

Two converging lenses with focal lengths of 50 cm and 19 cm are 12 cm apart. A 3.5-cm-tall object is 25cm in front of the 50-cm-focal-length lens.
