U1 L1: The Microscope

What is the best definition for a Compound Light Microscope?

• A type of microscope that only uses light from the sun to illuminate specimens.
• An electronic microscope that requires a vacuum to operate.
• An optical microscope that uses multiple lenses to magnify small objects.
• A device that uses only one lens to view large objects.

What is the best definition for an Objective Lens?

• A lens in an optical instrument that focuses light from the object to form an image.
• A lens used solely for viewing distant objects.
• A lens that magnifies objects without forming an image that is viewable.

• A lens that only collects light without focusing it.

What is the best definition for the Body Tube of a microscope?

• The body tube is the section that adjusts the focus of the microscope.
• The body tube is the part of the microscope that holds the eyepiece and connects it to the objective lenses.
• The body tube is the area where the light source is located.
• The body tube is the part that holds the stage of the microscope.

What is the best definition for the Revolving Nosepiece of a microscope?

• A fixed part that magnifies the specimen.
• A light source that illuminates the slide.
• A stage that holds the microscope slide.
• A rotating component that holds and allows the selection of different objective lenses in a microscope.

What is the best definition for the Stage of a microscope?

• The stage is the part that holds the eyepiece of the microscope.
• The stage is the light source used for illumination.
• The stage is the lens that magnifies the specimen.
• The stage is the platform where the specimen slide is placed for viewing.

What is the best definition for the Stage Clips of a microscope?

• Stage clips are used to adjust the focus of the microscope.
• Stage clips are a type of lens used in microscopy.
• Stage clips are used to secure the microscope slide on the stage.
• Stage clips are used to illuminate the slide on the stage.

What is the best definition for a Slide in relation to the microscope?

• A slide is a flat piece of glass or plastic used to hold specimens for microscopic examination.
• A slide is a container for storing microscope lenses.
• A slide is a type of microscope used for viewing specimens.
• A slide is a mechanism that adjusts the focus of a microscope.

What is the best definition for the Diaphragm of a microscope?

• The diaphragm is a type of microscope that uses mirrors.
• The diaphragm of a microscope is a component that controls the amount of light reaching the specimen.
• The diaphragm is a part that holds the objective lenses.
• A diaphragm is used to magnify the specimen.

What is the best definition for the Coarse Adjustment Knob of a microscope?

• A knob that allows for large adjustments in focus on a microscope.
• A knob that fine-tunes the color of the microscope light.
• A knob that adjusts the stage height for specimen placement.
• A knob that controls the magnification level of the microscope.

What is the best definition for the Fine Adjustment Knob of a microscope?

• A knob used to change the objective lenses of the microscope.
• A knob that controls the light intensity of the microscope.
• A knob that adjusts the stage height of the microscope by moving it large amounts.

• A knob that allows for precise focusing of the microscope.
