Question
A microscope is made of a combination of two converging lenses, called the objective lens and the eyepiece or ocular lens. In the lab you will assemble a model microscope very similar to the one shown in the figure below.
Both lenses and the object are aligned along the x axis, with the objective lens at x = 0. 1.
1. We want the image due to the objective lens alone to be located at point P (1.0 cm to the right of focal point F2). Where should we place the object? Give the position x of the object (in cm).
2. What is the lateral magnification due to the objective lens alone? (Remember the answer may be negative.)
3. The image formed by the objective is the object for the eyepiece lens. Where is the location of the final image? Give the position x in cm.
Explanation / Answer
1. -13.22 cm
2. -3.1
3. 25
4. 5
5. -15.5
