Front

What is the function of the low power objective in a microscope?

Back

The low power objective is used to view larger areas of the specimen and provides a lower magnification, making it easier to locate the area of interest.

Front

What is the formula for calculating total magnification in a microscope?

Back

Total magnification = Ocular lens magnification x Objective lens magnification.

Front

What part of the microscope is referred to as the medium power objective?

Back

The medium power objective is an objective lens that typically provides a magnification of 10X or 40X, allowing for a balance between detail and field of view.

Front

When carrying a microscope, which parts should you hold?

Back

You should hold the base and the arm of the microscope.

Front

What are stage clips used for in a microscope?

Back

Stage clips are used to hold the slide in place on the stage of the microscope.

Front

What is the purpose of the ocular lens in a microscope?

Back

The ocular lens, or eyepiece, is the lens you look through to see the magnified image of the specimen.

Front

What does the term 'magnification' mean in the context of microscopy?

Back

Magnification refers to the process of enlarging the appearance of an object, allowing for detailed observation of small specimens.

Front

What is the role of the diaphragm in a microscope?

Back

The diaphragm controls the amount of light that reaches the specimen, enhancing visibility and contrast.

Front

What is the difference between high power and low power objectives?

Back

High power objectives provide greater magnification and detail but have a smaller field of view compared to low power objectives.

Front

What is the base of a microscope?

Back

The base is the bottom part of the microscope that supports the entire structure and provides stability.
