The Fine Adjustment Knob is used to make small adjustments to the focus of the microscope, particularly when using high power objectives.

Front

What is the source of light in a microscope?

Back

The source of light in a microscope is typically a light bulb or LED, which illuminates the specimen for better visibility.

Front

How do you calculate total magnification in a microscope?

Back

Total magnification is calculated by multiplying the magnification of the ocular lens by the magnification of the objective lens.

Front

What is the role of the diaphragm in a microscope?

Back

The diaphragm controls the amount of light that passes through the slide, allowing for better contrast and visibility of the specimen.

Front

Where does the slide sit on a microscope?

Front

What is the typical magnification of an ocular lens?

Back

The typical magnification of an ocular lens is 10X.

Front

What happens to the field of view as magnification increases?

Back

As magnification increases, the field of view decreases, meaning you see a smaller area of the specimen.

Front

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

Back

Stage clips hold the slide in place on the stage to prevent it from moving during observation.
