The three objective lenses on a compound microscope are typically labeled as low power (4x), medium power (10x), and high power (40x). Each lens has a specific magnification power that allows for viewing specimens at various levels of detail.
1. A low power lens for simple observations.
2. A medium power lens for closer observations.
3. A high power lens for descriptive observations.

What is the function of an objective lens on a microscope?
Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.usually, there are three or four objective lenses on a microscope,
Explain why an inverted image is seen under a compound microscope?
An inverted image is seen under a compound microscope due to the multiple lenses in the optics system. The objective lens produces a real inverted image of the specimen, which is then further magnified by the eyepiece. This combination of lenses results in the final image appearing inverted when viewed through the eyepiece.
What is the objective lens on a microscope?
The objective lens on a microscope is the lens closest to the specimen being observed. It magnifies the specimen and gathers light to form an enlarged image for viewing. Different objective lenses have varying magnification levels.
What is the difference between a monocular microscope and a stereo microscope?
A monocular microscope has only one eyepiece, which provides a magnified view of a specimen in 2D. A stereo microscope, on the other hand, has two eyepieces that allow for binocular viewing, providing a three-dimensional (3D) view of the specimen with depth perception. Stereo microscopes are typically used for dissecting or examining larger specimens due to their 3D capabilities.
What parts do compound microscope?
A compound microscope consists of several key parts, including the eyepiece, objectives (lenses), stage, coarse and fine focus knobs, illuminator, condenser, and diaphragm. These components work together to magnify the specimen, control lighting, and focus the image for observation.
Does a compound microscope have one lens?
A compound microscope has two lenses: the objective lens and the eyepiece lens. The objective lens is used to gather light from the specimen and create a magnified image, which is further magnified by the eyepiece lens for viewing.
Attached to the revolving nosepiece of a microscope are three or four small lenses called?
They are called objective lenses.
What is the objective on a microscope?
the objective is the lens, there is the main ocular lens which you look through and then this leads to the turret. on the turret are 3 (usually) objective lenses which are usually 4x, 10x and 40x. so the objective are three lenses which change the amount of magnification on the microscope. :)
What are the three magnifications of the object lens?
Low power (4x), medium power (10x), and high power (40x) are the three magnifications typically found on a compound microscope's objective lenses.
The is what the 3 objective lenses are attached to?
The three objective lenses are typically attached to a rotating nosepiece on a microscope. The nosepiece allows for easy selection of the desired magnification by rotating the lenses into position above the specimen. This configuration enhances the versatility and efficiency of the microscope during observation.
What is the function of an objective lens on a microscope?
Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.usually, there are three or four objective lenses on a microscope,
What mechanical part of the microscope holds the three objectives?
The revolving nosepiece is the mechanical part of the microscope that holds the three objectives. It allows you to easily switch between different magnifications by rotating the nosepiece to select the desired objective lens.
How many lenses does the light pass through between the light source and your eye?
A typical eyepiece in a compound microscope consists of multiple lenses. Light passes through at least two lenses in a compound microscope - one in the objective lens and another in the eyepiece - before reaching your eye.
Which part of an optical microscope contains the magnifying lens?
The magnifying lens in an optical microscope is located in the eyepiece. This lens helps enlarge the image produced by the objective lens, allowing the viewer to see details not visible to the naked eye.
Explain why an inverted image is seen under a compound microscope?
An inverted image is seen under a compound microscope due to the multiple lenses in the optics system. The objective lens produces a real inverted image of the specimen, which is then further magnified by the eyepiece. This combination of lenses results in the final image appearing inverted when viewed through the eyepiece.
What are the degree of magnifications of microscope objectives?
Microscope objective lenses typically have magnification levels ranging from 4x to 100x. The magnification power is usually marked on the objective lens itself. Higher magnifications require the use of immersion oil to achieve clearer images.
What is the objective lens on a microscope?
The objective lens on a microscope is the lens closest to the specimen being observed. It magnifies the specimen and gathers light to form an enlarged image for viewing. Different objective lenses have varying magnification levels.
