Question

assessment 4.1: label the parts of a microscope.

Explanation:

To label the parts of a microscope, we identify each component:

• Head: The top part holding ocular lenses.
• Ocular lenses (Eyepiece): For viewing, magnifies the image.
• Body (Tube): Connects head to arm, holds optical parts.
• Objective lenses: Attached to the revolving nosepiece, provide magnification.
• Revolving Nosepiece (Turret): Holds objective lenses, rotates to switch them.
• Stage: Platform to place the slide, has clips to hold it.
• Stage Clips: Secure the slide on the stage.
• Arm: Supports head and stage, connects to base.
• Coarse Adjustment Knob: For large - scale focus adjustments.
• Fine Adjustment Knob: For fine - tuning focus.
• Condenser: Focuses light onto the specimen.
• Diaphragm (Iris Diaphragm): Controls light intensity.
• Light Source (Illuminator): Provides light for viewing (below the stage, near the base).
• Base: The bottom part, provides stability.

Answer:

• Head: The upper part containing ocular lenses.
• Ocular lenses: The eyepieces for viewing.
• Body: Connects head and arm, optical path.
• Objective lenses: Magnify the specimen, on the nosepiece.
• Revolving Nosepiece: Holds and rotates objectives.
• Stage: Holds the slide.
• Stage Clips: Secure the slide.
• Arm: Supports head and stage.
• Coarse Adjustment Knob: Rough focus adjustment.
• Fine Adjustment Knob: Precise focus adjustment.
• Condenser: Focuses light on specimen.
• Diaphragm: Controls light intensity.
• Light Source: Illuminates the specimen.
• Base: Supports the microscope.
