Exploring the Parts of a Compound Microscope

What is the primary purpose of the two lenses in a compound light microscope?

• To decrease magnification

• To increase magnification

• To adjust the light intensity

• To change the color of the specimen

Where is the first lens located in a compound light microscope?

• In the light source

• In the eyepiece

• In the arm

• In the base

What is the function of the coarse adjustment knob?

• To hold the slide in place

• To move the stage up and down for focusing

• To change the magnification

• To adjust the light intensity

Which part of the microscope holds the different objectives?

• The base

• The revolving nosepiece

• The arm

• The stage

What should you do first when setting up the microscope for use?

• Turn on the light source

• Remove the dust cover

• Place the slide on the stage

• Adjust the coarse adjustment knob

Why should you avoid using the coarse adjustment knob when switching to high power?

• It will change the magnification

• It will move the stage too slowly

• It will turn off the light source

• It can break the slide and damage the lens

What should you do if the microscope appears dirty?

• Use a coarse adjustment knob to fix it

• Turn off the light source

• Ignore it and continue using it

• Clean it with a lens cleaner

What is the pointer in the eyepiece used for?

• To point out a specific structure on the slide

• To adjust the light intensity

• To change the magnification

• To hold the slide in place

How do you calculate the total magnification of a specimen?

• Divide the magnification of the ocular lens by the objective lens

• Subtract the magnification of the ocular lens from the objective lens

• Multiply the magnification of the ocular lens by the objective lens

• Add the magnification of the ocular lens and the objective lens

If the ocular lens is 10x and the low power objective lens is 5x, what is the total magnification?

• 15x

• 50x

• 10x

• 5x
