For question 8, how would the ray diagram look like? 7. A convex (converging) lens has a focal length with an absolute value of 120 mm. An object is placed200 mm from the lens.a. Is the image real or virtual?b. What is the magnification of the image? (Is it upright or inverted?)C.Where is the image located?d. Draw a ray diagram for the situation. Use a ruler and make the diagram to scale.8. A convex (converging) lens has a focal length with an absolute value of 240 mm. An object is placed144 mm from the lens.a.Is the image real or virtual?C.Where is the image located?b. What is the magnification of the image? (Is it upright or inverted?)d.

A microscope has an objective lens with a focal length of 16.22 mm and an eyepiece with a focal length of 9.50 mm. With the length of the barrel set at 29.0 cm, the diameter of a red blood cells image subtends an angle of 1.43 mrad with the eye. It the final image distance is 29.0 cm from the eyepiece, what is the actual diameter of the red blood cell? Hint: To solve this question, go back to basics and use the thin-lens equation.
