What type of microscope would you use to observe the surface details of a specimen at very high magnification?

• A) Compound Microscope

• B) Electron Microscope

• C) Stereo Microscope

Which is not a safety step we discussed for the use of compound microscopes?

• Always carry the microscope with two hands, one on the base and one on the arm.

• Always plug in the microscope close to where wet mount slides are prepared.

• Never use the coarse adjustment knob at the highest power.

• Wash your hands after using wet mount slides with organic matter.

What is the primary function of the coarse adjustment knob on a compound microscope?

• To fine-tune the focus of the specimen.

• To adjust the light intensity.

• To bring the specimen into general focus.

• To change the magnification level.

What is the role of the diaphragm on a compound microscope?

• To adjust the amount of light reaching the specimen.

• To change the magnification level.

• To hold the slide in place.

• To focus the image.

Which part of the microscope is used to switch between different objective lenses?

• Stage

• Nosepiece

• Eyepiece

• Base
