To locate a specimen on a microscope, you typically start with the low-power objective lens, usually 4x or 10x. This magnification provides a broader field of view, making it easier to find the specimen. Once located, you can switch to a higher power objective lens for more detailed observation. Always ensure to use the coarse focus knob with low power and the fine focus knob with higher magnifications for clarity.
You should use the lowest value lens. It is the shortest one.
A microscope that has more than one lens is a compound microscope
A microscope typically uses multiple lenses, including both concave and convex lenses, to magnify and focus the light coming from the specimen being observed. The objective lens, which is closer to the specimen, is usually convex, while the eyepiece lens, which is closer to the observer's eye, is usually convex.
A light microscope uses a combination of convex lenses, including objective lenses and eyepiece lenses, to magnify and focus light passing through the specimen. The objective lens is closer to the specimen and creates the initial magnified image, while the eyepiece lens further magnifies the image for viewing by the observer.
Turning the coarse adjustment knob of a microscope downwards brings the objective lens closer to the specimen, allowing for initial focusing at low magnification. This is useful for quickly bringing the specimen into view. Turning the coarse adjustment knob upwards moves the objective lens away from the specimen, enabling a higher focal point for fine-tuning the focus at higher magnifications. It is essential to use the coarse adjustment first to avoid crashing the objective lens into the specimen, which can damage both the lens and the specimen.

You should start by using the lowest power objective lens, usually the 4x or 10x objective, to locate and center the specimen on the slide. Once the specimen is in focus, you can switch to higher magnifications for more detailed viewing.
The low power objective lens in a light microscope is manipulated by rotating the nosepiece to engage the correct lens. Then, use the coarse focus knob to move the objective lens close to the specimen until it is in focus. Finally, use the fine focus knob to fine-tune the focus for a clear view of the specimen.
You should start with the lowest magnification lens, typically the scanning lens (4x or 5x), to locate and center the specimen on the slide. This allows you to get a general overview of the slide before increasing the magnification with higher-power objectives.
A convex lens is used in a microscope to magnify the image of the specimen being examined. The shape of the lens allows it to focus light rays and produce a larger, clearer image for observation.
When viewing a specimen, you must always use the lower power objective lenses first. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.

You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
A microscope typically uses multiple lenses, including both concave and convex lenses, to magnify and focus the light coming from the specimen being observed. The objective lens, which is closer to the specimen, is usually convex, while the eyepiece lens, which is closer to the observer's eye, is usually convex.
The high power lens of a microscope is used to magnify the image of the specimen to show details that are not visible with lower magnification. It is typically used to observe finer structures and smaller details of the specimen.
The objective lens on a microscope is used to magnify the specimen being viewed. It is responsible for producing a magnified image that can be further examined using the eyepiece lens. Different objective lenses offer varying levels of magnification to provide detailed views of the specimen.
Coverslips are used on microscope slides to protect the specimen from damage and contamination, while also minimizing distortion and providing a flat surface for viewing. Additionally, coverslips help to prevent the objective lens from coming into direct contact with the specimen, which could potentially damage either the lens or the specimen.
