Let's solve this labeling task step by step. We are given a diagram of a compound light microscope with 14 numbered parts to label, and a list of possible terms on the right side.
Step 1: Understand the structure of a compound microscope
A compound microscope has several key components:
-
Eyepiece (ocular lens) – where you look through.
-
Objective lenses – located near the specimen, usually multiple lenses (low, medium, high power).
-
Revolving nosepiece (turret) – holds the objective lenses and allows switching between them.
-
Stage – platform where the slide is placed.
-
Stage clips – hold the slide in place.
-
Diaphragm (iris diaphragm) – controls the amount of light passing through the specimen.
-
Condenser – focuses light onto the specimen.
-
Arm – connects the base to the head.
-
Base – supports the entire microscope.
-
Adjustment knobs – coarse and fine for focusing.
-
Lamp – light source.
-
Barrel – the tube connecting the eyepiece to the objective lenses.

Now, let’s match each number to the correct part:
Matching the labels:
1.
Top of the microscope, where you look through →
Eye Piece
2.
The rotating part that holds the objective lenses →
Revolving nose
3.
The lens closest to the specimen (usually one of the objectives) → Since there are multiple lenses, but the lowest one is typically the
Low power objective Lens
4.
Next objective lens up →
Medium power Objective Lens
5.
Highest magnification lens →
High power objective lens
6.
Platform where the slide is placed →
Stage
7.
Clips that hold the slide on the stage →
Stage clips
8.
The circular opening below the stage where light passes through →
Iris Diaphragm
9.
The long tube connecting the eyepiece to the objectives →
Barrell
10.
The arm that supports the upper part →
Arm
11.
The large knob used for initial focusing →
Coarse adjustment knob
12.
The smaller knob for fine focusing →
Fine adjustment knob
13.
The light source at the bottom →
Lamp
14.
The base that supports the microscope →
Base

Final Answer:
1.
Eye Piece
2.
Revolving nose
3.
Low power objective Lens
4.
Medium power Objective Lens
5.
High power objective lens
6.
Stage
7.
Stage clips
8.
Iris Diaphragm
9.
Barrell
10.
Arm
11.
