Web1. Use the 75mm focal length convex lens (#14), a crossed arrow target as the object (#8), a viewing screen (#11), and 2 element holders (#22) to hold the lens and screen in your design. Set up the optical bench as in Figure 12.1. Place the lamp at one end of the bench and direct its illumination parallel to the bench axis using the knob on the ... Webuse the optical bench to measure u and v for several images in order to obtain a value for the focal length of the biconvex lens. The sign convention for equation (12.1) is that v is taken to be positive to the right of the lens and negative to the left. Procedure Place the object on the optical bench near one end, and place
