A higher power objective lens in a microscope is used when greater magnification is needed to study an object.
The higher power objective lens has a shorter focal length and needs to be closer to the object being studied. It has a smaller aperture (lens diameter) so it has a narrower field of vision and may require more light to be useful. This means that it is more difficult to find and center the item being studied under the lens and it is harder to focus the lens on the object.

What is high low objective in a microscope?
In microscopy, the high-low objective refers to the use of multiple objective lenses with varying magnifications, typically a high-power lens (e.g., 40x or 100x) and a low-power lens (e.g., 10x or 20x). The low-power objective is used for scanning and locating areas of interest on a specimen, while the high-power objective allows for detailed observation of specific structures. This combination enables efficient examination and detailed analysis of samples in biological and material sciences.

What are the three objectives found on the microscope you used in class?
The three objectives typically found on a classroom microscope are the low power objective (usually 4x or 10x magnification), the medium power objective (often 10x or 40x magnification), and the high power objective (commonly 40x or 100x magnification). These objectives allow users to view specimens at varying levels of detail, enabling both a broader overview and a more focused examination of specific features. Each objective is designed to be easily rotated into place, facilitating quick transitions between different magnifications.
Which part of a microscope should be used with the low power objective but not with the high power objective?
The coarse focus knob should be used with the low power objective but not with the high power objective. The point of using the coarse focus knob is to bring the specimen into general focus before fine-tuning with the high power objective, which requires more precise adjustments.

The coarse adjustment knob on a microscope should never be used with the?
The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.
When should the high power objective be used?
The high power objective should be used when you need to examine smaller details or structures in a specimen at higher magnification. It provides a higher magnification level compared to the low power objective, allowing you to see finer details.
What is the function of medium power objective in a microscope?
The medium power objective in a microscope is used for observing specimens at a higher magnification than the low power objective, but not as detailed as the high power objective. It is commonly used to examine finer details of a specimen while still maintaining a wider field of view than the high power objective.
What is a high power objective in a microscope?
A high power objective in a microscope is a lens that provides high magnification of the specimen being viewed. It typically magnifies the image by 40x to 100x, allowing for detailed observation of fine structures. High power objectives are used for examining smaller details and are typically used after lower magnification objectives.
Why should the course-adjustment knob on a microscope not be used with a high-power objective lens?
The course-adjustment knob moves the stage up and down quickly, and using it with a high-power objective can potentially damage the objective or slide due to a rapid change in focus. It is best to use the fine-adjustment knob when using a high-power lens for precise focusing.
Why should you only use the fine adjustment knob when you are using high power?
The fine adjustment knob should be used with high power magnification because it allows for smaller, more precise movements of the objective lens. This helps to prevent damage to the slide and objective lens, as well as minimize the risk of crashing the objective lens into the slide.
