What is the best definition of resolution as it relates to a microscope?

• The color depth of an image.
• The size of the image file in bytes.
• The speed at which an image is processed.
• The clarity or detail of an image or display.

How can you determine total magnification of a microscope?

• Total magnification = Eyepiece magnification - Objective magnification
• Total magnification = Eyepiece magnification x Objective magnification
• Total magnification = Eyepiece magnification + Objective magnification
• Total magnification = Eyepiece magnification / Objective magnification
