What is the function of the stage on a light microscope?

The stage is where the microscope slide is placed and held in place by a slide holder or clip.

What is the magnification power of the eyepiece (ocular) lens on a light microscope?

The eyepiece lens typically has a magnification of x10.

What are the common magnification powers of the objective lenses on a light microscope?

Common magnification powers are x4, x10, x40 and x100.

How do you initially bring an image into focus on a light microscope?

Use the coarse focus knob while looking through the eyepiece lens with the lowest powered objective lens (x4).

What is the purpose of adding dye to a sample on a microscope slide?
