Low power (4x), medium power (10x), and high power (40x) are the three magnifications typically found on a compound microscope's objective lenses.
As the object is moved closer to a converging lens or mirror, the image distance decreases, and the image becomes larger and more magnified. When the object is moved away from the lens or mirror, the image is formed farther away, becomes smaller, and less magnified.
The low-power objective lens (usually 4x) is always used first to locate an object on a microscope. This objective lens provides a wider field of view and a lower magnification, making it easier to find and center the specimen before moving to higher magnifications.
This describes a compound microscope, which usually consists of an objective lens that magnifies the image of an object and an eyepiece that further magnifies the image for viewing. This combination allows users to observe objects at higher magnifications with clarity.
You need a lens, an object to view, and a light source to magnify an object. The lens will help in focusing the light and enlarging the object, while the light source will help illuminate the object for better visibility.
The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.

The lens of a compound microscope closest to the object being examined is called the objective lens. This lens is responsible for gathering light from the specimen and magnifying the image. It typically comes in various magnifications, such as 4x, 10x, 40x, and 100x, allowing for different levels of detail to be observed.
When focusing on an object using a microscope, you should always start with the lowest power objective lens first (usually the scanning lens, 4x), then move to the medium power lens (10x), and finally to the highest power lens (40x or higher). This order helps prevent damage to the slide and the lens, and makes it easier to locate and focus on the specimen. Always ensure the stage is lowered when switching to higher magnifications to avoid crashing the objective into the slide.
The objective lens that shows the greatest amount of detail is typically the oil immersion lens, usually a 100x objective. This lens uses a special oil to reduce light refraction, allowing for better resolution and clarity of fine details. Higher magnification objectives, such as 40x or 60x, also provide good detail but not as much as the oil immersion lens. Always start with lower magnifications to locate your specimen before switching to higher magnifications for detailed observation.

There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.

The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.
A virtual image of an object through a concave lens is always upright, reduced in size, and appears on the same side of the lens as the object. Its location depends on the distance of the object from the lens and the focal length of the lens.
