Problem 1 A single thin lens is used to create an image of a 10.0 cl source that is located at position x-0 crm (30.0 cm to the left of the lens), as show in the figure below. The magnitude of the radius of curvature for the font (left) surface Sr is IR, -50.0 cm madc of ZnSc with an index of refraction of 2.42 (a) What is the magnitude and sign of radius of curvature for the back (right) surfacc Re? Sketch the back and the focal length f- +20.0 cm, respcctivcly. Thc lens is surfacc S of the lens in the figure below, indicating which way the surfacc curves and if that curvaturc is greater or less than that of the front surface. (5 points) (b) Using two principal rays, show the resulting imagc. (6 points) (c) Using the propoer formula(s), calculate the position x where the image get formed? Please use the coordinate system that is provided in the figure below. (5 points) (d) What is the height h of the image? (5 points) (e) Is the image upright or inverted (upright pointing up, inverted-pointing down)? Is it real (all rays are actually passing through the image) or virtual? (4 points) Diens-2.42 Rh?
