- 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: A ray parallel to the axis, after reflection, passes through the focal point F of a concave mirror or appears to come from the (virtual) focal point of a convex mirror. A ray through (or proceeding toward) the focal point F is reflected parallel to the axis. 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. A ray to the vertex V is reflected, forming equal angles with the optic axis. 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.A concave mirror is to form an image of the filament of a headlight lamp on a screen 7.00 m from the mirror.
