Two convex lenses which share a common principal axis are separated by a distance which is greater than the sum of their focal lengths, as shown. 1 F F F F2 lens 1 lens 2 Lens 1, with focal length F1, is placed to the left. Lens 2, with focal length F2, is placed a distance L to the right of the first lens. A 11% Part (a) An object is placed a distance do,1 =28 cm to the left of lens 1 which has focal length F1 =5.8 cm. Ignore the existence of lens for the moment. What is the position of the image, di, created by lens 1? Include the sign which is consistent with standard sign conventions.
