The total magnification of a compound microscope is calculated by multiplying the magnification of the ocular lens (usually 10x) with the magnification of the objective lens. If the lowest power objective has a magnification of 4x, then the total magnification would be 40x (10x * 4x).
You place the object on the stage of the microscope when you are viewing it. The stage is the flat platform where the specimen is positioned for observation under the lens.
Objective lenses are located beneath the microscope stage, facing the specimen. They are usually mounted on a revolving nosepiece so that different objective lenses with varying magnifications can be easily switched during observation.
When viewed under the Low Power Objective (LPO), the image of the specimen appears larger and allows for a broader field of view, making it easier to locate and assess the overall structure and layout of the specimen. In contrast, the High Power Objective (HPO) provides a more magnified and detailed view, allowing for closer examination of specific features or cells within the specimen. However, the field of view is smaller under HPO, making it necessary to reposition the slide to observe different areas. Overall, LPO is useful for initial observations, while HPO is essential for detailed analysis.

Under a low power objective, the letter "e" would appear larger and more defined compared to a higher magnification. It may appear clearer and easier to discern the details of the letter.
low power objective lens to locate and focus on the specimen before moving to higher magnifications.
The total magnification of a compound microscope is calculated by multiplying the magnification of the ocular lens (usually 10x) with the magnification of the objective lens. If the lowest power objective has a magnification of 4x, then the total magnification would be 40x (10x * 4x).
If you completely lose focus while viewing a specimen under high power, you should first move the fine adjustment knob in both directions to try and regain focus. If that doesn't work, switch back to a lower magnification objective lens, refocus the specimen, and then switch back to the high power objective to try focusing again.
when viewing objects under high-power, the field of view is smaller, but you are able to see more details.
when viewing objects under high-power, the field of view is smaller, but you are able to see more details.
when viewing objects under high-power, the field of view is smaller, but you are able to see more details.
When viewing a specimen under the microscope, you should always start with the lowest magnification objective lens. This allows you to locate and focus on the specimen before moving to higher magnifications for a closer look.
