The Microscope

Our microscopes magnify the specimen using two lenses therefore it is called:

• a binocular microscope

• a dual lense microscope

• a compound microscope

• an electron microscope

This part of our microscopes magnifies the image 40 times.

• low power objective

• high power objective

• medium power objective

• ocular objective

The diaphragm on a microscope:

• enlarges the image

• flips the image upside down

• adjusts the light on the image

• focuses the image

This focus knob moves the stage up and down the most.

• fine adjustment knob

• medium adjustment knob

• coarse adjustment knob

• high adjustment knob

When using the medium power objective on our microscopes, the total magnification is:

• 20X

• 40X

• 100X

• 400X

This pictures shows:

• onion cells

• elodea cells

• cheek cells

• liver cells

This picture shows that the microscope:

• only flips images upside down

• only flips images over backwards

• flips the image upside down and backwards

• doesn't flip the image at all

This part of the microscope holds the objective lenses.

• stage

• revolving nosepiece

• diaphragm

• ocular

Item #8, the bottom one on the left side, is pointing to the:

• diaphragm

• light source

• stage

• base

Low power is 5X, medium power is 15X and high power is 25X. The eyepiece is 5X. What is the total magnification when using medium power?

• 3X

• 20X

• 50X

• 75X
