Microscope - Worksheet Solution

Microscope is a scientific instrument that is used to observe tiny objects or organisms that cannot be seen with the naked eye. It has a magnifying lens or a combination of lenses that can enlarge the image of the object being observed.

Parts of a Microscope:

1. Eyepiece: The eyepiece is the part of the microscope that one looks through. It contains a magnifying lens that enlarges the image of the object being observed.

2. Objective lens: The objective lens is the part of the microscope that is closest to the object being observed. It contains one or more lenses that enlarge the image of the object being observed.

3. Stage: The stage is the platform on which the object being observed is placed. It also has clips or holders to hold the object in place.

4. Diaphragm: The diaphragm is a disc with different sized holes that is located under the stage. It controls the amount of light that enters the microscope.

5. Light source: The light source provides the light that illuminates the object being observed. It is usually located below the stage.

Types of Microscopes:

1. Compound Microscope: A compound microscope is a type of microscope that uses two or more lenses to magnify the object being observed. It is commonly used in laboratories and schools.

2. Stereo Microscope: A stereo microscope is a type of microscope that provides a three-dimensional view of the object being observed. It is commonly used for dissecting or examining larger objects.

Applications of Microscopes:

1. Medical Sciences: Microscopes are extensively used in medical sciences for diagnosing and studying diseases.

2. Biology: Microscopes are used in biology to study the structure and function of cells and tissues.

3. Material Sciences: Microscopes are used in material sciences to study the structure and properties of materials.

In conclusion, a microscope is an important scientific instrument that is used to observe tiny objects or organisms that cannot be seen with the naked eye. It has various parts like eyepiece, objective lens, stage, diaphragm, and light source. There are different types of microscopes, including compound and stereo microscopes. Microscopes have various applications in medical sciences, biology, and material sciences.

A microscope is an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.
