Exploring the Microscope

What is the main function of the eyepiece in a microscope?

• To focus the light on the specimen.

• To illuminate the specimen.

• To magnify the image of the specimen.

• To hold the specimen in place.

Name the three common types of objective lenses found in microscopes.

• Objective lens for fluorescence

• Phase contrast objective

• Scanning objective, Low power objective, High power objective

• Wide field objective

What is the purpose of the illumination system in a microscope?

• To magnify the specimen for detailed observation.

• To focus the light on the microscope's lenses.

• To adjust the temperature of the specimen during observation.

• To illuminate the specimen for better visibility and contrast.

How does the stage of a microscope assist in viewing specimens?

• The stage adjusts the color of the specimen for contrast.

• The stage magnifies the specimen for better clarity.

• The stage supports and positions the specimen for optimal viewing.

• The stage illuminates the specimen from below.

What is the role of the slide in microscopy?

• The slide magnifies the specimen for better visibility.

• The slide is used to adjust the focus of the microscope.

• The slide illuminates the specimen from below.

• The slide holds the specimen in place for observation under the microscope.

Why is it important to clean the lenses of a microscope?

• To prevent the microscope from overheating.

• It is important to clean the lenses of a microscope to ensure clear visibility and accurate observations.

• To make the microscope look new and shiny.

• To ensure the microscope is properly calibrated.

What should you do if a microscope is not focusing properly?

• Use a different microscope altogether.

• Clean the table the microscope is on.

• Replace the light bulb in the microscope.

• Adjust the focus knobs and check the lens alignment.

How can you prevent dust from accumulating on the microscope?

• Store the microscope in a humid environment.

• Leave the microscope uncovered at all times.

• Use a dust cover and maintain a clean workspace.

• Use a wet cloth to clean the lenses frequently.

What is the function of the coarse focus knob?

• To make large adjustments to the focus of a microscope.

• To stabilize the microscope on the table.

• To change the objective lens of the microscope.

• To adjust the brightness of the microscope.

Describe one way to properly store a microscope after use.

• Disassemble the microscope and store parts separately.

• Store the microscope in direct sunlight.

• Leave the lenses dirty for next use.

• Clean the lenses and cover the microscope with a dust cover.
