Question

7. It is above the body tube wherein the ocular or the eyepiece
is placed​

Answer 1

Answer:

Above the stage and attached to the arm of the microscope is the body tube. This structure houses the lens system that magnifies the specimen. The upper end of the tube contains the ocular or eyepiece lens. The lower portion consists of a movable nosepiece containing the objective lenses

Answer 2

Answer:

The right response is Draw tube.

A draw tube is a tiny tube that is mounted above the body tube and holds the eyepiece or the ocular.

Explanation :

• An optical device called a compound microscope allows one to clearly view structures that are too small to be seen with the unaided eye. It consists of networks of lenses with various magnifications.
• The ocular or eyepiece has one pair of lenses, and the objectives have the other set.
• Because of the combination of these lenses, the item being seen is larger, increasing the magnifying power of the microscope.
• The compound microscope's resolving power is another feature.
• It is the capacity to distinguish between items and present them in diverse perspectives in order to highlight their distinct contrasts and produce crisp images with fine details.

• Although pricey, a microscope is a crucial instrument in scientific research. It must be handled carefully.

The mechanical parts of it are as follows :

1.Horseshoe base, the component that supports the entire microscope, is the first mechanical component.

2. The portion that rises upward from the base to hold the stage and support all other parts is referred to as a pillar.

3. Inclination hinge or joint - the part that enables the microscope to be tilted at a desired angle.

4. Stage, when the item to be examined is placed

5. Stage clips: These hold the slide firmly in place.

6. Arm - supports the body tube and is mostly used to support the microscope as it is being carried.

7. Body tube: A cylindrical structure with the eyepiece at the top and the objectives at the lower end.

8. Draw tube: The ocular or eyepiece is placed in a tiny tube that is mounted above the body tube.

9. Wheels that raise or lower the tube are known as adjustments.

10. Dust shield, the spherical disc that sits on top of the rotating nosepiece and shields the objectives from dust.

11. Rotating nosepiece carries and rotates the goals.
