The illumination lights in an operating room use a concave mirror to focus an image of a bright lamp onto the surgical site. One such light has a mirror with a focal length of 11.0 cm. Use ray tracing to find the position of its lamp when the patient is positioned 1.4 m from the mirror (you'll need a careful drawing to get a good answer). Do this on paper. Your instructor may ask you to turn in this work.
