Lens 2, with focal length F2, is placed a distance L to the right of the first lens. Part (a) An object is placed a distance do1 =26.5 cm to the left of lens 1 which has focal length F =4.8 cm. Ignore the existence of lens 2 for the moment. What is the position of the image, di1 created by lens 1? Include the sign which is consistent with standard sign conventions. Numeric : A numeric value is expected and not an expression. di1 = Part (b) Calculate the magnification, M1, of lens 1 for the object as positioned in the previous step. Be certain to include the sign that is consistent with the standard conventions. Numeric : A numeric value is expected and not an expression. M1 = Part (c) Which statement best describes the image created by lens 1? MultipleChoice : 1) The image is real and inverted. 2) The image is real and upright. 3) The image is virtual and upright. 4) The image is virtual and inverted. Part (d) Lens 2 is placed a distance L = 20.0 cm to the right of lens 1, and the image of lens 1 becomes the object of lens 2. Calculate the object distance, do2, relative to lens 2. Be certain to include the sign as consistent with the standard sign conventions. Numeric : A numeric value is expected and not an expression. do2 Part (e) Which statement best describes the object for lens 2? MultipleChoice : 1) The object is a virtual object because the outgoing rays diverge. 2) The object is a real object because the outgoing rays diverge. The object is a real object because the incoming rays converge. 3) The object is a virtual object because the incoming rays converge. 4) Part () Lens 2 has focal length F2 =8.75 cm. What is the position of the final image relative to lens 2, di2, created by lens 2? Include the sign which is consistent with standard sign conventions. Numeric A numeric value is expected and not an expression. d; 2 = Part (g) Calculate the magnification, M2, of lens 2 only. This is the magnification for the process that forms the final image from the intermediate image that was created by lens 1. Be certain to include the sign that is consistent with the standard conventions. Numeric : A numeric value is expected and not an expression. M2 = Part (h) What is the net magnification, Mnet of the two-lens system? Be certain to include the sign that is consistent with the standard conventions.
