Explain why it's important to follow the correct shut-down procedure for a microscope each time it is used.
Explain why it's important to follow the correct shut-down procedure for a microscope each time it is used.
Following the correct shut-down procedure ensures the longevity and optimal performance of the microscope by preventing damage and maintaining cleanliness.
A prepared slide is being viewed under a microscope. As you switch from the yellow objective to the blue objective, what happens to the field of view, and why does this change occur?
A prepared slide is being viewed under a microscope. As you switch from the yellow objective to the blue objective, what happens to the field of view, and why does this change occur?
The field of view decreases because the magnification increases, allowing for greater detail but less area to be viewed.
If you are viewing a specimen under the red objective, what is the total magnification? Show your work.
If you are viewing a specimen under the red objective, what is the total magnification? Show your work.
40x. 4x (red objective) * 10x (eyepiece) = 40x.

Study Notes
- The base is the bottom support of the microscope.
- The eyepiece is the lens you look through.
- The arm is the vertical support connecting the base and head.
- The fine focus knob allows for precise image focusing.
- Objectives are the lenses with different magnifications.
- The diaphragm controls the amount of light reaching the specimen.
- The coarse focus knob allows for large image focusing.
- The light source provides illumination for viewing the specimen.
- The stage is the platform where the specimen is placed.
- Stage clips secure the specimen slide on the stage.
- How to carry a microscope: one hand on the arm and one hand under the base.
- The magnification of the eyepiece is 10x.
- The total magnification of the yellow objective is 40x.
- The magnification of the red objective is 4x.
- The total magnification of the red objective is 40x.
- The magnification of the yellow objective is 10x.
- The total magnification of the blue objective is 400x.
- The magnification of the blue objective is 100x.
- Field of View (FOV) is what a person views or sees.
- 10x has less image, more detail.
- 4x has more image, less detail.
