Understanding Magnification in Compound Microscopes

What is the fixed magnification of the eyepieces in a compound microscope?

• 20x

• 15x

• 10x

• 5x

How can you determine the magnification of an objective lens?

• By checking the color of the lens

• By observing the magnification power indicated on it

• By measuring its length

• By calculating the diameter of the lens

Which of the following is NOT a common magnification for objective lenses?

• 10x

• 25x

• 4x

• 40x

How do you calculate the total magnification of a specimen viewed under a compound microscope?

• Add the magnification of the objective and eyepiece

• Multiply the magnification of the objective by the eyepiece magnification

• Subtract the eyepiece magnification from the objective magnification

• Divide the magnification of the objective by the eyepiece magnification

If you are using a 20x objective lens, what is the total magnification of the specimen?

• 800x

• 20x

• 200x

• 400x
