How to approach this question
Identify part C on the diagram. It is pointing to one of the lenses just above the stage. What is the primary purpose of lenses in a microscope?
Full Answer
D.To magnify the image of a specimen✓ Correct
To magnify the image of a specimen
The parts of the microscope shown are:
- **A: Focus knobs.** Used to bring the specimen into focus.
- **B: Mirror/Light source.** Illuminates the specimen.
- **C: Objective lens.** This is a key part of the magnification system. The total magnification of the microscope is calculated by multiplying the magnification of the eyepiece lens (the one you look through) by the magnification of the objective lens being used.
Common mistakes
✗ Confusing the objective lens with the eyepiece lens (though both magnify).\n✗ Confusing magnification with focusing or illumination.
