Microscopes

What is the function of the eyepiece in a microscope?

• To magnify the image and allow the viewer to see the specimen.

• To hold the specimen in place.

• To adjust the focus of the microscope.

• To control the intensity of the light source.

Name the three main parts of a compound microscope.

• mirror, condenser, arm

• base, diaphragm, focus knob

• nosepiece, stage clips, coarse adjustment knob

• eyepiece, objective lens, stage

What is the difference between a compound microscope and a stereo microscope?

• A compound microscope uses two lenses to magnify the specimen, while a stereo microscope uses two separate optical paths to provide a three-dimensional view of the specimen.

• A compound microscope uses one lens to magnify the specimen, while a stereo microscope uses two lenses to provide a three-dimensional view of the specimen.

• A compound microscope provides a higher magnification than a stereo microscope.

• A compound microscope is used for viewing small, transparent specimens, while a stereo microscope is used for viewing larger, opaque specimens.

What is the formula for calculating magnification?

• Image size + Object size

• Image size * Object size

• Image size - Object size

• Image size / Object size

What is the maximum magnification achievable by a light microscope?

• 2000x

• 3000x

• 500x

• 1000x

What is the relationship between magnification and resolution?

• Resolution is independent of magnification.

• Magnification and resolution are directly related.

• Magnification and resolution are inversely related.

• Magnification has no effect on resolution.

What are the two types of electron microscopes?

• X-ray microscope and fluorescence microscope

• Atomic force microscope (AFM) and scanning tunneling microscope (STM)

• Optical microscope and confocal microscope

• Transmission electron microscope (TEM) and scanning electron microscope (SEM)

What are the applications of a light microscope?

• Studying cells, tissues, microorganisms, observing biological processes, diagnosing diseases, conducting research

• Detecting radiation, examining fossils, observing celestial bodies

• Measuring temperature, analyzing chemical compounds, studying weather patterns

• Creating 3D models, analyzing DNA sequences, studying human behavior

What are the applications of a scanning electron microscope?
