What is the function of the eyepiece in a microscope?

Back

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

What is the total magnification if the ocular lens is 10X and the objective lens is 40X?

Back

The total magnification is 400X (10X ocular lens multiplied by 40X objective lens).

Front

What part of the microscope is used to adjust the focus?

Back

The coarse focus knob is used to move the stage up and down for focusing on the specimen.

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 a compound microscope and a simple microscope?

Back

A compound microscope uses multiple lenses for higher magnification, while a simple microscope uses a single lens.

Front

What is the function of the stage in a microscope?

Back

The stage is the platform where the slide containing the specimen is placed for observation.

Front

What does the term 'field of view' refer to in microscopy?

Back

Field of view is the visible area seen through the microscope eyepiece, which decreases as magnification increases.

What is the purpose of the base of a microscope?

Back

The base provides stability and support for the microscope, ensuring it remains upright during use.
