A plastic cylinder of length 2.71-101 cm has its ends ground to convex (from the rod outward) spherical surfaces, each having radius of curvature 1.19-101 cm. A small object is placed 1.19.101 cm from the left end. How far will the image of the object lie from the right end, if the index of refraction of the plastic is 1.46?

The magnification of an upright image that is 34.0 cm away from its object is 0.400. What type of lens is used to form the image, and what is its focal length?

A convex mirror with a radius of curvature of 25.0 cm is used to form an image of an arrow that is 10.0 cm away from the mirror. If the arrow is 2.00 cm tall and inverted (pointing below the optical axis), what is the height of the arrows image?

The radius of curvature of the left-hand face of a flint glass biconvex lens (n = 1.60) has a magnitude of 8.00 cm, and the radius of curvature of the right-hand face has a magnitude of 11.0 cm. The incident surface of a biconvex lens is convex regardless of which side is the incident side. What is the focal length of the lens if light is incident on the lens from the left?
