5:56 all56 @ ) Lab 13 Mirrors and Lenses Objective: Understand how to use ray diagram to find out location and shape of images created by concave mirror and convex lens. Theory The image of an object created by mirrors and lenses can be constructed via ray diagram method and following equation Where means the object distance, means image distance, and means focal length. If the are real, the sign is positive. If they are virtual, the sign is negative. Procedure: . Setup lightbulb (object) and mirror distances as listed in table 1, by adjusting the half screen in between to find a shape image of the object. Record the distance between the screen and mirror as image distance. . Setup lightbulb (object) and lens distances as listed in table 2, by adjusting the full screen on the other side of the lens to get a shape image of the object. 4. Record the distance between the screen and mirror as image distance. ~ \\US] Table 1 : Concave Mirror Focal length: 20 cm 5 points Object Describe the image Image Distance Image Distance Percentage Distance (Experimental) (Theoretical) error 55 cm 65 cm Graph: 5 points d2l.lonestar.edu (0 5:56 all56 @ ) Table 1 : Concave Mirror Focal length: 20 cm 5 points Object Describe the image Image Distance Image Distance Percentage Distance (Experimental) (Theoretical) error 55 cm 65 cm Graph: 5 points Table 2: Double Convex Lenses Focal length;__10cm 5 points Object Describe the image Image Distance Image Distance Percentage Distance (Experimental) (Theoretical) error 15 cm 30 cm Graph: 5 points d2l.lonestar.edu U 5:56 all56 @ ) Table 2: Double Convex Lenses Focal length:__10cm 5 points Object Describe the image Image Distance Image Distance Percentage Distance (Experimental) (Theoretical) error 15 cm 30 cm Graph: 5 points Questions: 1 point each 1.
