- an object is placed 19.0 cm to the left of a lenss of the focal length 12.0cm. 27.0 cm to the right of this lens is a plane mirror. Where does the final image form? - 5.56 cm to the right of the mirror -5.56 cm to the left of the mirro - 21.4 cm to the left of the lens -32.6 cm to the left of the lens -19.6 cm to the left of the mirrorOne side of a lens is convex with radius of curvature 30 cm. The other side is concave with radius of curvature 50 cm. The index of refraction of the lens is 1.6. What is the focal length of the lens? Group of answer choices 130 cm, converging 130 cm, diverging 31 cm, converging 31 cm, divergingA glass lens (?=1.60) has a focal length of ?=−32.7 cm and a plano‑concave shape. Calculate the magnitude R of the radius of curvature of the concave surface. R = ?cm If a lens is constructed from the same glass to form a plano‑convex shape with the same radius of curvature magnitude, what will the focal length f' be? f' = ? cm

- A contact lens is made of plastic with an index of refraction of 1.40. The lens has an outer radius of curvature of +1.92 cm and an inner radius of curvature of +2.47 cm. What is the focal length of the lens? cmA student attempts to determine the focal length of a mirror through graphical analysis. They make a series of observations by changing the position of an object and measuring the position of the corresponding focused image. When they graph their data to create a linear relationship, they obtain the following graph.

If an object is placed 53.4 cm in front of the lens, what is the magnification of the image produced?An ant is 6.8 cm tall and stands 1.9 cm in front of an unknown mirror. To its surprise the ant sees its image which is 2.4 cm tall, standing upright! What is the focal length of the mirror?You place an object 21.4 cm in front of a diverging lens which has a focal length with a magnitude of 11.8 cm. Determine how far in front of the lens the object should be placed in order to produce an image that is reduced by a factor of 3.35. cm Additional Materials
