Front

Define total magnification in microscopy.

Back

Total magnification is calculated by multiplying the eyepiece magnification by the objective lens magnification.

Front

What is the magnification power of the eyepiece lens in a typical microscope?

Back

Usually 10x.

Front

How do you calculate total magnification with a 10x eyepiece and a 4x objective lens?

Back

10x * 4x = 40x.

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

Back

To focus light and magnify the specimen.

Front

What is the difference between low power and high power objective lenses?

Back

Low power lenses have lower magnification (e.g., 4x) while high power lenses have higher magnification (e.g., 40x).
