Microscope Review

If a biologist uses a microscope with an eyepiece of 10x magnification and an objective lens of 5x, what is the total magnification observed?

• 30x

• 40x

• 50x

• 60x

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

• 10x + 4x = 14x

• 10x * 4x = 40x

• 10x - 4x = 6x

• 10x / 4x = 2.5x

What is the significance of using a cover slip when preparing a slide?

• To protect the specimen and prevent contamination.

• To enhance the visibility of the specimen under the microscope.

• To increase the thickness of the slide for better observation.

• To allow for easier handling of the slide during examination.

What is the magnification power of the medium power objective lens?

• 5x

• 10x

• 15x

• 20x

What is the function of the stage on a microscope?

• To illuminate the slide for better visibility.

• To hold the slide in place for viewing.

• To magnify the specimen being observed.

• To adjust the focus of the microscope.

What is the total magnification under medium power if the eyepiece is 4x and the medium power objective is 10x?

• 20x

• 30x

• 40x

• 50x

What is the magnification power of the low power objective lens?

• 2x

• 4x

• 10x

• 20x

Define total magnification in microscopy.

• Total magnification is the sum of the eyepiece magnification and the objective lens magnification.

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

• Total magnification is the maximum magnification achievable by a microscope.

• Total magnification is the difference between the eyepiece magnification and the objective lens magnification.

What is the importance of adjusting the focus knob on a microscope?

• To bring the specimen into clear view.

• To increase the magnification of the specimen.

• To change the light intensity on the specimen.

• To adjust the color balance of the image.

What is the magnification power of the high power objective lens?

• 10x

• 20x

• 30x

• 40x
