A compound microscope consists of two lenses, an objective lens (close to the object) and an eye lens (close to the eye). The objective lens forms a real image of the object close to the eye lens, from which the eye lens gives a greatly magnified virtual image.
What is compound microscope in 12th physics?
Hint: A compound microscope is a microscope which is constructed using two convex lenses, one of the lenses is kept near the eye while the other is kept near the object that is being viewed. The image formed by the objective lens serves as an object for the ocular lens.
What is compound microscope explain with example?
Compound-microscope definition
The definition of a compound microscope is a microscope with a lens that enlarges the viewed object and an eye piece that further enlarges it. An example of compound microscope is Galileo’s “little eye.” noun. 2. A microscope with more than one lens.
What is a microscope in physics?
A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses.
What is compound microscope Class 9?
A compound microscope is a type of microscope that uses two sets of lenses to magnify the image under the microscope. It has an objective lens that has a resolution of 4x,10x, 40x, 100x, and an eyepiece of resolution of 10x.
What is compound microscope?
What is Compound Microscope? A microscope with a high resolution and uses two sets of lenses providing a 2-dimensional image of the sample. The term compound refers to the usage of more than one lens in the microscope. Also, the compound microscope is one of the types of optical microscopes.
What is 12th microscope?
Microscope is an instrument that gives an enlarged image of minute object.
Why is it called compound microscope?
The compound light microscope is a tool containing two lenses, which magnify, and a variety of knobs used to move and focus the specimen. Since it uses more than one lens, it is sometimes called the compound microscope in addition to being referred to as being a light microscope.
Why is compound microscope called such?
The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. The lens closest to the eye is called the ocular, while the lens closest to the object is called the objective.
Where is the compound microscope used?
Used of a compound microscope. (1) It is used to observe blood corpuscales, plant and animals cells, microorganisms like bacteria, etc. (2) It is used in a pathalogical laboratory to observe blood, urine, etc. (3) It is a paret of a travelling microscope used for measaurement of very small distance.
What is simple and compound microscope?
The main difference between a compound microscope and a simple microscope is that the simple microscope uses a single lens that is used for reading like daily activity but the compound microscope has to work on more than one lens that makes a difference in clarity.
What is microscope short answer?
A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is. 5 – 12+ Biology, Engineering.
What are types of microscope?

- Scanning probe microscope.
What is difference between microscope and compound microscope?
A magnifying instrument that uses only one lens to magnify objects is called a Simple microscope.
Difference Between Simple And Compound Microscope.
| Characteristics | Simple Microscope | Compound Microscope |
|---|---|---|

What is compound microscope parts and functions?
The three basic, structural components of a compound microscope are the head, base and arm. Head/Body houses the optical parts in the upper part of the microscope. Base of the microscope supports the microscope and houses the illuminator. Arm connects to the base and supports the microscope head.
What are types of compound microscope?
A compound microscope can come in several types such as biological microscopes, polarizing microscopes, phase contrast microscopes, or florescence microscopes with uses varying for each.
Which is lens formula?
Let’s see how to use lens formula (1/v-1/u= 1/f) to locate images without having to draw ray diagrams.
What is astronomical telescope?
Definition of astronomical telescope
: a telescope that is designed for observing celestial bodies and that requires no image-erecting system — compare terrestrial telescope.
Who discovered microscope?
Zacharias Janssen
Every major field of science has benefited from the use of some form of microscope, an invention that dates back to the late 16th century and a modest Dutch eyeglass maker named Zacharias Janssen.
Why is compound microscope important?
Compound microscopes allow scientists to see microorganisms and cells.Without these microscopes, we would not know about the existence of cells and therefore would not be able to study DNA or make medical advances based on our knowledge of how different diseases or conditions attack cells.
