Answer:
The correct answer is B: Microscope.
A microscope is used to see objects that are too small for the unaided eye. It is a scientific instrument that magnifies small objects, allowing us to see them in greater detail. Here is a detailed explanation:
Definition and Purpose:
- A microscope is an optical instrument that uses lenses to magnify small objects.
- It is used to study and observe objects that are too small to be seen with the naked eye.
- Microscopes are commonly used in scientific research, medicine, biology, chemistry, and other fields.
Working Principle:
- Microscopes work by using a combination of lenses to magnify the image of an object.
- Light passes through or reflects off the object and enters the microscope.
- The lenses in the microscope focus the light and magnify the image, allowing it to be seen by the observer.
Types of Microscopes:
- There are several types of microscopes, each with its own specific purpose and function.
- Light microscopes use visible light to illuminate the specimen and magnify the image.
- Compound microscopes have multiple lenses and are commonly used in biology and medicine.
- Electron microscopes use a beam of electrons instead of light and can achieve much higher magnification.
Applications:
- Microscopes are used in various scientific and medical applications.
- They are used to study cells, microorganisms, tissues, and other small structures.
- In medicine, microscopes are used for diagnosing diseases, analyzing blood samples, and performing surgeries.
- In biology, microscopes are used to study the structure and function of living organisms.
In conclusion, a microscope is the correct tool to use when observing objects that are too small for the unaided eye. It allows us to see these objects in detail and has numerous applications in various scientific and medical fields.
