C. Producing virtual images The eyepiece of a microscope produces a virtual image to be viewed by the eye, i.e. the rays of light that form the final image diverge from the lens and appear to come from a location behind the eyepiece lens (the image appears to be behind the lens).
1. Make a ray diagram for a converging lens (focal length f) with the object at a distance s < f.

The compound microscope consists of two converging lenses: the objective and the eyepiece. Suppose the focal length f_1 of the objective is 20 cm, and the focal length f2 of the eyepiece is 20 cm. The separation between the objective and eyepiece is 66 cm. The object is located 30 cm in front of the objective. (These numbers are not realistic for a real microscope.) a. Calculate the location and magnification of the image, and state whether it is a...

Design a microscope with a 20X objective, 160 mm tube length and an eyepiece that produces another 1.5X of visual magnification. For simplicity, you may put the image for the eye at infinity. Begin your design with a drawing of the situation. Then graphically trace your rays through the system. You should be able to answer the following questions when your design is complete: What is the focal length of the objective lens in mm? For the previous question's microscope...

A compound microscope has an objective lens of focal length 10.0 mm with an eyepiece of focal length 15.5 mm , and it produces its final image at infinity. The object to be viewed is placed 2.0 mm beyond the focal point of the objective lens. a. How far from the objective lens is the first image formed? b. What is the overall magnification of this microscope?

6. A compound microscope consists of two converging lenses (the objective and the eyepiece) placed 7.0 cm apart. If the first lens (objective) has a focal length of 2.8 mm and the second lens (eyepiece) has a focal length of 3.3 cm, what would be the location of the final image of an object placed 3.0 mm from the objective lens? Describe the image
