Exploring the Light Microscope

What is the purpose of the condenser lens in a light microscope?

• To magnify the specimen

• To focus light on the specimen

• To adjust the light level

• To hold the slide in place

Which part of the microscope is used to adjust the level of light?

• Objective lens

• Eyepiece lens

• Diaphragm

• Coarse focus knob

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

• Add the magnifications of the objective and eyepiece lenses

• Multiply the magnifications of the objective and eyepiece lenses

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

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

What is the magnification of the high power objective lens mentioned in the prompt?

• 4 times

• 10 times

• 40 times

• 100 times

If the eyepiece lens magnifies 10 times and the scanning objective lens magnifies 4 times, what is the total magnification?

• 14 times

• 40 times

• 400 times

• 100 times

Which knob should be used for fine-tuning the focus of a specimen?

• Coarse focus knob

• Fine focus knob

• Stage knob

• Diaphragm

What is the function of the stage knobs on a microscope?

• To move the stage up and down

• To adjust the light level

• To move the stage side to side

• To change the objective lens

What should you use to clean the lenses of a microscope?

• Regular tissue

• Lens paper

• Cotton cloth

• Microfiber cloth

What is a wet mount used for in microscopy?

• To dry the specimen

• To prepare a specimen for viewing

• To stain the specimen

• To magnify the specimen

What should you do before putting away the microscope?

• Leave the slide on the stage

• Turn off the light and lower the stage

• Increase the light level

• Leave the high power objective lens in place
