In this article, I will take you through 25+ most frequently asked questions about microscope. The evolution of science led to invention of many magnificent instruments which continues to provide an integrated support to research and development. Microscope is one such invention which helps us viewing all the microbes and other non-living ultra smaller things that cannot be seen through naked eye. Microscope find its usage in many places such as Labs, Schools, Colleges, Research Centres etc. Here we will see some of the most frequently asked questions about microscope in below section.
25+ Most Frequently Asked Questions About Microscope
1. What is a Microscope ?
Ans. A microscope is an instrument used to view and magnify small objects or organisms that are not visible to the naked eye.
2. Who invented Microscope ?
Ans. The invention of the microscope is often credited to multiple individuals, including Zacharias Janssen and his father Hans in the late 16th century, as well as Antonie van Leeuwenhoek in the 17th century.
3. Which microscope is often used to view metal surfaces ?
Ans. The scanning electron microscope (SEM) is often used to view metal surfaces.
4. What does a diaphragm do on a microscope ?
Ans. The diaphragm on a microscope controls the amount of light that enters the instrument and helps to improve contrast and clarity in the image.
5. What does the coarse adjustment knob do on a microscope ?
Ans. The coarse adjustment knob on a microscope is used to move the stage up and down to bring the specimen into focus.
6. Which was the first cell viewed by the light microscope ?
Ans. The first cell viewed by the light microscope is believed to be a cork cell by Robert Hooke in 1665.
7. Which microscope did Robert Hooke used to study tree bark ?
Ans. Robert Hooke used a compound microscope to study tree bark.
8. What is resolution in microscope ?
Ans. Resolution in a microscope refers to the ability to distinguish two closely spaced objects as separate entities.
9. When was the microscope invented ?
Ans. The microscope was invented in the late 16th century, with various individuals contributing to its development and refinement over time.
10. What does the condenser do on a microscope ?
Ans. The condenser on a microscope collects and focuses light onto the specimen, improving image clarity and resolution.
11. What does the stage do on a microscope ?
Ans. The stage on a microscope is where the specimen is placed for observation, and can be moved up and down or side to side to adjust the viewing position.
12. How to focus a microscope ?
Ans. To focus a microscope, start with the lowest magnification objective lens and use the coarse adjustment knob to bring the specimen into focus, then fine-tune the focus using the fine adjustment knob.
13. What are parts of microscope ?
Ans. The different parts of a microscope are as follows:-
- Objective lenses
- Fine adjustment knobs, and
- Light source
14. What does a worm look like under a microscope ?
Ans. A worm may look elongated and segmented under a microscope, with small bristles and appendages visible on its body.
15. What is a Compound Microscope ?
Ans. A compound microscope is a type of microscope that uses multiple lenses to magnify a specimen, typically using transmitted light.
16. What is a light Microscope ?
Ans. A light microscope is a microscope that uses visible light to illuminate a specimen and magnify it.
17. Which two microscopes generate three dimensional images ?
Ans. The confocal microscope and the electron microscope can both generate three-dimensional images of a specimen.
18. Where is the nose piece on a microscope ?
Ans. The nosepiece on a microscope holds the objective lenses and can be rotated to change the magnification level.
19. What is an electron microscope ?
Ans. An electron microscope is a type of microscope that uses a beam of electrons to view and magnify specimens, providing much higher magnification and resolution than a light microscope.
20. Which microscope achieves the highest magnification and greatest resolution ?
Ans. The electron microscope achieves the highest magnification and greatest resolution of any type of microscope.
21. What does the ocular lens do on a microscope ?
Ans. The ocular lens on a microscope is the lens closest to the eye and is used to view the magnified image of the specimen.
22. What part of the microscope controls the amount of light ?
Ans. The diaphragm on a microscope controls the amount of light that enters the instrument and can be adjusted to control the brightness of the image.
23. What does the stage clips do on a microscope ?
Ans. The stage clips on a microscope are used to hold the specimen in place on the stage and prevent it from moving during observation.
24. What does parfocal mean in microscope ?
Ans. Parfocal in a microscope means that when you switch between objective lenses, the specimen remains largely in focus, minimizing the need for extensive refocusing.
25. When do we use a fluorescence microscope labster ?
Ans. A fluorescence microscope is used in labster to visualize fluorescently labeled specimens, such as proteins or cells, by exciting them with light and detecting the resulting fluorescent signal.
26. What is the working distance of a microscope ?
Ans. The working distance of a microscope is the distance between the objective lens and the specimen when it is in focus, and can vary depending on the magnification level and type of objective lens used.
