12. What are the 3 microscope powers and their magnification?
• 4x magnifies 40 (scanning power)
• 10x magnifies to 100 (low power)
• 40x magnifies to 400 (high power)
13. What power do you use when turning on and off the microscope?
4x- scanning power
14. What is Resolving Power?
The measure of light passing throught the lens.
15. The lower the RP, the more _________ the image appears.
clear
16. Why do we calibrate a microscope?
The distances between the spaces on the ocular micrometer vary depending on the which objective is being used.  Therefore the microscope has to be calibrated at each power in order to ensure accurate measurements.

19. Interpupilary distance is
the measurement of how far apart your eyes are.
20. Distance between the objective and the slide is called the
working distance
21. The parfocal feature on a microscope allows
the image to remain in focus as the objectives are rotated.
22. NA stands for what and means what?
• Numerical Aperture
• a measure of the amount of light permitted to enter the objective. Determines lens quality.
23. Inversion refers to
when you view an image under the microscope, it appears upside down and reversed.
