The following question are about two-lens systems and microscopes. Remember the following facts about a two lens system: . The object for the second lens is located at the location of the image from the first lens. . The total magnification of the system is the product of the magnifications of each lens. 1 1 point This question and the next four are all based on the following prompt: An amoeba is 0.305 cm away from the 0.300 cm focal length objective lens of a microscope. An eyepiece with a 2.00 cm focal length is placed 20.0 cm from the objective lens. Where is the image formed by the objective lens? Make your answer positive if it is a real image and negative if it is a virtual image. Express your answer in cm. Type your answer... 2 1 point What is this image's magnification? Your answer should be positive if the image is upright, and negative if the image is inverted. Type your answer... 3 1 point What is the location of the final image (i.e. the image created by the eyepiece)? The location should be with respect to the eyepiece lens. Make your answer positive if the image is real and negative if the answer is virtual. Express your answer in cm. Hint: The diagram in Figure 26.16 in your text is very helpful for thinking about distance and locations in a microscope. Type your answer...4 1 point What magnification is produced by the eyepiece? Your answer should be positive if the image is in the same orientation that it was in after the objective lens, and it should be negative if it is in the opposite orientation as it was after the objective lens. Type your answer... 5 1 point What is the total magnification of the microscope. Your answer should be positive if the final image is in upright relative to the original object, and negative if it is inverted relative to the original object. Type your answer... 2 points This question and the next are related. Where does an object need to be placed relative to a microscope objective lens for the 0.500 cm focal length objective to produce a magnification of -400? Express your answer in cm. Type your answer... 7 2 points Relating to the previous question, how far from the objective lens should a 5.00 cm focal length eyepiece be placed to create a further 4.00 X magnification? Express your answer in cm. Hint: The diagram in Figure 26. 16 in your text is helpful in thinking about distances and locations in a microscope. Type your
