The illumination lights in an operating room use a concave mirror to focus an image of a bright lamp The illumination lights in an operating room use a concave mirror onto the surgical site. One such light has a mirror with a focal length of 15.0 cm. Use ray tracing to find the position of its lamp when the patient is positioned 1.6 m from the mirror (you'll need a careful drawing to get a good answer).

Use the thin lens equation to solve this.
(1/s)+(1/s prime)=(1/f)
You are looking for the s value, which is the lamp's distance from the mirror. s prime is the distance to the patient, and f is 15 cm.
(1/s)+(1/1.6)=(1/.15)
Your answer should be 16.55 cm.
(1/s)+(1/s prime)=(1/f)
