- A concave mirror has a radius of curvature of R = 0.699 m. An object is place p = 0.910 m away from the mirror. How far (q) from the mirror does the image form? Your answer should be in meters (m).A person’s eye has a diameter of 2.5 cm and a converging lens that produces a clear, real image on the retina. When viewing an apple, the eye’s lens has a focal length of 2.4 cm. What is the distance between the apple and the person’s eye?A convex mirror has a focal length of –29 cm. What is the object distance if the image distance is –17 cm? Answer in units of cm.
