Microscope Lab Questions

magnification is how large you can make an object, resolution is the ability to distinguish between two objects

Describe the difference between resolution and magnification

as magnification increases the field of view and depth decrease

Describe the relationship between depth of field and magnification

both light microscopes, stereo also used during dissection of plants and animals, compound have two systems of lenses.

Name a difference and similarity between a stereomicroscope and a compound microscope

as magnification increases, field of view decreases

Relationship between magnification and field of view?

working distance decreases as the magnification increases

Relationship between working distance and magnification of the objective?

400x

Total magnification of a specimen, using your microscope, with the 40x objective in place?

when you have light at different wavelengths and the oil eliminates the air between the cover glass and the objective lens

Under what circumstances should you use an oil immersion lens?

when you change from one lens to another, the same part of your slide is centered in your field of view

What does the term "parcentral" mean and how does it apply to microscope use?

a lens on a microscope that stays in focus when the magnification is changed

What does the term "parfocal" mean and how does it apply to microscope use?

the view is zoomed in

What happens to your field of view as you change from the 4x objective to the 10x objective?

that its better to use low power objective
