Identifying parts that magnify and focus specimens.

Step 1: Identify the labeled parts of the microscope

To find which part changes magnification, let's identify what each letter points to:

• A: Eyepiece (ocular lens) – the lens you look through, which has a set magnification (usually \(10\times\)).
• B: Body tube – connects the eyepiece to the objective lenses.
• C: Objective lens – the lenses closest to the specimen. There are usually multiple objective lenses with different magnifying powers (e.g., \(4\times\), \(10\times\), \(40\times\)) mounted on a rotating nosepiece.
• D: Stage clip – holds the slide in place.
• E: Stage – the flat platform where the slide is placed.
• F: Mirror / Light source – directs light up through the specimen.

Step 2: Determine which part changes magnification

• To change the magnification of the specimen you are viewing, you rotate the revolving nosepiece to select a different objective lens (labeled C).
• Switching between these lenses (such as moving from low power to high power) directly changes how much the image is magnified.

Answer:

C (Objective lens)
