Question

Place the order (First, Second, Third, Fourth, Fifth) next to the object in the order that it occurs in a microscope, beginning with the eye to the specimen on the stage.
1. First ocular lens 12. Second coverslip 53. Third revolving nosepiece 34. Fourth body tube 25. Fifth objective lens 4

Answer 1

Answer:

1. Ocular lens.

2. Body tube.

3. Revolving nosepiece.

4. Objective lens.

5. Coverslip.

Explanation:

1. The ocular lens is closest to the eye. It is the piece through which we see.

2. The body tube allows light to pass from below up through the microscope into our eye.  The ocular lens attaches to it.

3. The revolving nosepiece is down below and allows us to change the magnification to use with the specimen. It holds the objective lenses.

4. Objective lens. We select the required objective lens by turning the revolving nosepiece. It is closest to the specimen.

5. Coverslip. This is a glass that is used as support. It is where we place the specimen.

Answer 2

Answer:

The correct order starting from next to the object is

1. coverslip

2. objective lens

3. revolving nosepiece

4. body tube

5. body tube

Explanation:

The correct order starting from next to the object is

1. coverslip

2. objective lens

3. revolving nosepiece

4. body tube

5. body tube

A cover slip is a glass that is used to cover the specimen before observing through a microscope. Thus it is the nearest to the object.

Objective lens is the one which is near to the object hence it comes after the coverslip.

Revolving nose piece is a setup to which the objective lenses are attached thus it will come after the objective lens

Body tube is the hollow and tubular structure that forms the upper part of microscope.

While ocular lens also known as eyepiece are the farthest from the object , hence they come at the last.
