Which safety rule should you always follow when carrying a microscope?
Carry it by the eyepiece only
Carry it with both hands, one on the arm and one under the base
Carry it by the stage
Carry it with one hand
What does the term "resolution" mean in microscopy?
The ability to magnify an image
The ability to distinguish two close objects as separate
The amount of light passing through the specimen
The size of the specimen
Which part of the microscope holds the slide in place?
Stage clips
Objective lens

Base
Why should you start focusing with the lowest power objective lens?
It gives the highest magnification
It is easier to find and focus on the specimen
It uses less light
It is safer for your eyes
Which type of microscope uses a beam of electrons instead of light to form an image?
Light microscope
Electron microscope
Dissecting microscope
Stereo microscope
What is the function of the stage on a microscope?
To adjust the focus
To support the slide being observed
To magnify the specimen
To adjust the light intensity
If you want to increase the resolution of your image, what should you do?
Use a lower power objective lens
Use a higher power objective lens with a smaller wavelength of light
Use less light
Use a thicker specimen
Which part of the microscope do you look through to see the specimen?
Objective lens
Eyepiece
Stage
Base
What should you do if you spill a chemical on a microscope?
Ignore it
Wipe it off with a dry tissue
Inform your teacher and clean it up safely
Wash the microscope under running water
Which microscope part is responsible for changing the objective lenses?
Stage
Revolving nosepiece
Coarse focus knob
Diaphragm
What is the main advantage of using an electron microscope over a light microscope?
It is cheaper
It is smaller and portable
It has a much higher resolution
It is easier to use
Which of the following is NOT a safe practice when using a microscope?
