O2 Intro to Cells and Microscopy

Front

What is the formula to calculate total magnification in microscopy?

Back

Total Magnification = Eyepiece Magnification x Objective Lens Magnification.

Front

If the eyepiece has a magnification of 10 and the objective lens has a magnification of 40, what is the total magnification?

Back

Total Magnification = 10 x 40 = 400.

Front

What is the function of the fine adjustment knob on a microscope?

Back

The fine adjustment knob is used to make small adjustments to focus the image, especially at higher magnifications.

Front

What happens to the field of view as magnification increases?

Back

As magnification increases, the field of view decreases.

Front

Which objective lens provides the smallest field of view?

Back

The high power objective provides the smallest field of view.

Front

What is the magnification of a microscope with a 10X eyepiece and a 55X objective lens?

Back

Total Magnification = 10 x 55 = 550.

Front

What is the purpose of the coarse adjustment knob on a microscope?

Back

The coarse adjustment knob is used to make large adjustments to the focus of the image.

Front

Define 'field of view' in microscopy.

Back

Field of view is the visible area seen through the microscope eyepiece.

Front

What is the relationship between magnification and resolution in microscopy?

Back

Higher magnification does not always mean better resolution; resolution is the ability to distinguish two close points as separate.

Front

What type of microscope uses light to magnify specimens?

Back

A light microscope uses visible light to magnify specimens.
