High power objectives provide high magnification for detailed observation of small structures, while low power objectives offer a wider field of view for locating specimens and getting a general overview of the sample. Switching between high and low power objectives allows for both detailed examination and context within a specimen.

A high-power microscope, such as an electron microscope, is used to visualize the endoplasmic reticulum. The intricate structure of the endoplasmic reticulum requires high magnification and resolution to observe its details effectively.

The low power objective typically has a lower magnification level (e.g., 4x or 10x) compared to the high power objective (e.g., 40x or 100x), and it usually has a wider field of view. The high power objective will provide a closer magnified view of the specimen but with a narrower field of view. You can often find the magnification level labeled on the side of the objectives.

When changing from medium to high power on a microscope, you should not touch the coarse focus knob. This knob is used to adjust the focus at lower magnifications and can cause the objective lens to crash into the slide if used at high power, potentially damaging the slide or the lens.

When changing objectives from low power to high power on a microscope, it is necessary to first ensure the current objective is retracted, then rotate the nosepiece to position the desired high power objective in place. Refocusing will also be required due to the change in magnification levels.

A low power objective is essential on any microscope, It allows you to quickly scan a large area of the specimen, and to locate those areas which need closer study with a high power objective. For example, a histologic section of liver might measure 20 by 40 mm. With a 4x objective you can scan the entire piece of tissue in a minute or less. If there is a 1 mm tumor somewhere in the section, you will find it during this scan, and can them zoom in on it with the high power objectives. Trying to scan the entire slide with a 40x objective would take a long time because in any given field you can see only 1/100 the surface area included in a 4x scan), and you could easily miss a 1 mm tumor entirely. but this didnt helpso hanks aot for nothing

They are kind of like zooms. The higher the power the closer you can see, the lower the power the farther out you can see. There are different size powers though. Most ofter the more expensive the microscope the higher and/or more powers it has.

Using high power objectives can lead to decreased depth of field, making it more difficult to keep the specimen in focus. Additionally, high power objectives are more sensitive to vibrations and movements, which can result in blurry images. Finally, using high power objectives increases the risk of damaging both the objective lens and the specimen due to the close proximity between them.
