Question 10 An objective lens for a TEM has an effective focal length of 0.25 cm and is positioned 0.255 cm after the sample. (a) Make a sketch and show the ray diagram for the objective lens and indicate the location of the image plane and object plane. Determine the location and magnification of the image formed by the objective lens.  (4) (b) A second lens is position beyond the first one. The image is located at 17.05 cm from the second lens and magnifies the first image by an additional factor of 7.5. How far is the second lens from the first lens and what is its focal length?   (5) (c) What is the total magnification of the double lens system?   (1) (d) An atom is about 1 Å in size.  How large a magnification do you think you need to see an atom using a perfect detector with pixel size of 20 microns?  Justify your answer.   (2)

Extra Credit (5 Points): One morning while swimming in the Gulf of Mexico, Alphonso swims directly into the path of an evil sea monster, which bites off part of his left arm. The resulting blood loss sends Alphonso into shock by the time he is rescued. His symptoms include paleness, cool skin, tachycardia, and a weak pulse. Explain each of these symptoms in detail using correct physiological terminology.  Your answer should explain how and why they have occurred based on the body’s responses to this type of crisis.  You should summarize the short-term and long-term responses based on what you learned in Chapter 20 about blood pressure regulation.
