Please help with data and analysis portion Height of object = 43cm Focal length = 47 cm
Measure and record the size of the object, h. Place the lens 100 cm from the object and size of the image, h' , in a table like the one shown below: (the light source), locate the image on the screen. Record the image distance q, P(cm) q(cm) h' (cm) 100 87 -36.5 120 76 -28 140 70 -21 160 65 -18 180 63 -15 Analysis Compute, for each trial, the focal length of the lens using Equation 1. Compute the average value of the focal length. Compute, for each trial, the size of the image using Equation 2. Results Summarize the results of this exercise in a table like the one shown below: h' (cm) h' (cm) (measured) (calculated) p(cm) f (cm) 100 120 140 180

outside the window). The distance of the screen from the lens is the focal length. Locate on the screen the focus of parallel rays from a distant object (something dord tis on the sketch. (We cannot get perfect value from the online lab) Part II For a near object as shown below the obiect distance p, image distance q, the focal length are all related by the lens equation, which is 1 1 1 +-= (1) p q f Sketch The ratio of the size of the image to the size of the object is the magnification, M, of the lens. The magnification is related to the object and image distances by M=-! (2) Data 2
