PHY 1520 - Activity 8: Chapter 26 - Image Formation by Mirrors and Lenses For all problems, please show explicitly the work that you have done to arrive at your answer. It is helpful to note the property you have used to arrive at your answer & to include such equation before inserting numerical values. Remember to include units & to mind your significant figures! You may find it helpful to draw a diagram even if is not required. 1. A converging lens has a focal length of 2 cm. An object 1.5 cm in height is placed 6 cm from the lens. Construct a ray diagram, find the image distance, and describe the image. Confirm your answers by using the Lens equation. 2. Consider the object-concave mirror system shown. (a) Label the focal point with an F, the radius of curvature with C, and the object with O. (b) Draw the ray diagram (at least 3 rays) for light originating at the tip of the object. (c) Draw the image. (d) If the distance from the object to the mirror is 9 m and the radius of curvature is 2.5 m, find the distance from the image to the mirror. Is the image real or virtual
