5. I am a Class 10 student, my board exams are coming soon. Can I get proper guidance and required help on the topic of parts of a compound microscope?

A very important step that you shall be doing after you are done with your preparation and revisions are taking up some quizzes. This may really help you to analyse your preparation and identify your strengths and weaknesses which can be used to make the next immediate plan of action. They make you confident and make it easier for you to recognize your next set of actions which also saves your time. To conclude, it helps you in so many ways, and you may make sure you attempt all the steps of your learning journey in an organized manner and that too at the right time.

The team sends its 5-15s to her on a Thursday morning. Marshall says she reads the reports quickly and tries to acknowledge them swiftly, before taking 15 minutes to summarize the achievements and concerns noted by her staff. “As a manager I find it absolutely invaluable, because it highlights things I might have missed,” Marshall said.

The tool is called a “5-15” and works like this: Each week, everyone on a team spends 15 minutes writing feedback in a templated report sent to the team’s manager. The manager takes five minutes to read and respond to each report, and 15 minutes to collate their own feedback for their manager. This continues up the chain. Done right, it provides those at the very top of even the most complex company a weekly snapshot of what’s going well and badly from the point of view of all their employees.

If you are using an oil immersion lens, the oil should always be used for accurate results. As without the use of oil, the refractive index may be changed, which manipulates the reading of the specimen.

The 5-15 was first thought up by Yvon Chouinard, the now 80-year-old pioneering founder of Patagonia, a company famed for its environmental ethics and its engagement with employees’ and managers’ well-being (notably, it has retained new mothers through its on-site childcare, for example.) Since the tool’s genesis in the mid-1980s, its proponents have made clear that it is designed to free up those at the heads of teams and companies, not load them with extra work. Chouinard famously spent months away from the office rock climbing and surfing, and used the 5-15s as a way of keeping a finger on the company’s pulse. Other executives have since taken it on, adapted it, and even invented their own versions.

Mirror: A concave mirror on one side and plain mirror, on the other hand, can be seen below the stage to focus the light on the stage for a brighter image of the specimen.

The specimen must be first focused under the low-resolution lens, then later high-resolution lens must be used to target it furthermore.

Of course! Vedantu offers you all the sample papers from previous years that will help you understand the pattern of question papers and gain knowledge. You will also be able to learn to manage time during the examination. To get them, visit their website or download their Mobile App.

4. I want a summary of all the important formulas that can be used while solving questions from various topics and also, diagrams from topics like parts of a compound microscope. Is it possible?

For better concept clarity, Vedantu provides you with the best teachers who will be there to help you with the best possible solutions. Since they offer everything that you need to prepare well, your success is sure. You can find details on the mentioned topic available on this page.

It is one of the most ancient techniques used to make learning more effective. The Feynman technique is like teaching others. There could be two ways to do that, either pick up a study partner and teach them or if you're someone who is shy, you can also consider teaching to an imaginary audience. Studies show that when you teach someone else, you can know where you stand and monitor your learnings. This technique also helps you to gain more confidence and thus, the final results are elevated.

Clips: The stage, on the side of the specimen holder, contains clips that hold the slides on which samples will be placed.

Sarah Marshall is head of audience growth for Vogue International, based in London. She joined Condé Nast International, Vogue’s parent company, when it was in a process of rapid growth, and says the 5-15 process, which was already being used at the company, has helped her manage her team of 10 effectively.

2. My medical exams are approaching and I want to revise concepts like parts of a compound microscope better. What should I do?

If you are using a high-resolution lens for a specimen, the fine adjustment knob should only be employed. Do not use the coarse adjustment knob as it cannot give accurate results for viewing smaller details.

The person viewing the microscope should place the lens in a well-lit place so that an adequate amount of light strikes the concave part of the mirror under the stage.

Always use a coverslip on the slide of the specimen. This ensures other particles do not accumulate on the sample and alter the results.

Eyepiece: It is the lens used on the upper part of the body tube. It usually has a resolution of 10x but can be of 5x or 15x. It is the lens through which the person views the specimens.

Since exam season is around the corner, students might be spending a lot of their time figuring out the best technique to get ready for the final day. But you cannot afford to waste a lot of time just planning about it because you shall be taking action. There are a lot of techniques that are scientifically proven and guarantee results. Read ahead to know about a few of them!

The person using the lens must first arrange the eyepiece. They must arrange the mirror in a manner that the maximum amount of light reaches at the end of the stage. This ensures that the specimen has adequate light for viewing.

Inclination Joint: It is the point where the pillar meets the arm. The whole microscope can tilt at this inclination joint.

The 5-15s follow a set format and are often divided into bullet points below a set of headings: highlights of the week; people met with; challenges; plans for next week; and plans for the next four weeks. Other possible categories include “lessons learned” or “areas for improvement” (Marshall notes that organizations can customize the process as they see fit).

Yes, sure! It is possible with Vedantu. From preparation for your school exams to board exams and from olympiads to competitive exams — they have got it all! Let nothing stop you because this is yours to explore.

Nose piece: The body tube has three holes that have places to fit the objective lens. This structure is called the nose piece.

You may stick to the 80/20 rule which is also known as Pareto’s Principle. It states that 20% of your tasks/activities will bring you 80% of the results/awards. Try to find out what is more important and spend time on those. Find out these tasks and focus on them. Spend less time on tasks that may not be productive. They may entertain you now but they will not contribute as much value as other tasks would. So, manage your time as it is precious. Make sure that you are able to put yourself into action even in the most challenging and difficult times because that is how you can get closer to your dreams.

“In the past I have had slightly frustrating responses from people I’ve sent messages up the chain to,” she says of using it at other companies. “As a manager, it’s important to think about how you respond to 5-15s. In my personal view it’s good to use it as a team-building tool for encouragement and positive feedback.”

A more unobstructed view of the specimen is obtained when the coarse adjustment knob in the microscope is used. The fine adjustment knob gives an accurate picture of the sample.

The resolution of the eyepiece remains constant, but the resolution of the objective lens can be changed by rotating the nose piece. Hence, the same microscope can be used to view the object of focus in different magnifications.

Fine adjustment knob: It is a tiny knob that is used for focusing on the slide accurately. This knob can make only small adjustments.

The eyepiece and objective lens must be cleaned by silk cotton and transparent liquid, so that dust accumulated on the lens does not hinder the viewing of the slide or focus.

Students must have thoroughly understood about what is a compound microscope, what are its parts and the working mechanism along with the precautions through the above-shared content.

Stage: It is the rectangular structure that has a hole in the center that allows the light to pass through it. It is below the eyepiece, and most of the specimens are placed on this stage to examine.

Certainly! Students are not required to waste their time searching and preparing a separate sheet of paper for writing all the important formulas together or making the diagrams. Vedantu has done that for you, check it on the website.

If you want more resolution on the same specimen, the nose piece is turned into a higher resolution. At this point, only a fine adjustment knob should be used as a coarse adjustment knob can crush the slide.

It’s self-evident that good communication between managers and the people who report to them makes for a better culture at work. But “good communication” is a goal, not a strategy. That’s why you’ll find many companies using a simple, 30-year-old technique that takes a few minutes each week and can, if used correctly, keep managers in the loop right to the top of an organization, and ensure everyone has a chance to be heard.

Diaphragm: It is a structure located below the stage which controls the intensity of light entering the stage. It is of two types: disc and iris.

As with all tools, the specifics of implementation are key. Writing the feedback shouldn’t take too long, and needs to be received with encouragement and good grace, Marshall says.

When a person is using the coarse adjustment lens, care should be taken that the objective lens does not touch the slide of focus. Sometimes, the coarse adjustment lens, when used rapidly, may crush the specimen to be observed, and precise results cannot be obtained, and  the example and the slide also may be damaged.

Always use a clean slide or clean the slide with proper water and wipe it so that any stains on the slide do not appear under the microscope. This can confuse the person whether the perceived object is a stain or a part of the specimen.

Objective lens: It is the lens used on the lower part of the body tube. It is attached to the nose piece. Usually, three or four nose pieces are available, which contain the objective lens of different resolutions like 10x, 40x, 100x.

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. The usage of both lenses, compounds or magnifies the image of the object below the objective lens to achieve a resolution of 40x, 100x, 400x, 1000x.

The microscope must not be disturbed by tilting or shaking it while using it. This bouncing alters the light received by the lens, and the viewing of the object of focus alters.

First, the specimen must be focused under the low-resolution objective lens by coarse adjustment. Any necessary diagrams can be drawn by viewing from this resolution.

The beauty of the process is its simplicity and swiftness, but also the format, which allows those who might find it hard to bring up an issue even in a one-on-one meeting to air it in a “safe space.” Marshall says she enjoys reading the achievements of her team and will try to solve challenges then and there, if she can. If not she includes them in her own “challenge” section.

The primary principle used here is the principle of compounding or magnification. The magnification factor of the eyepiece multiplied with that of the objective lens. This principle produces a magnified image.

Prioritizing tasks while you prepare yourself for exams is an important thing to do. You can use several techniques which will make the process easy and effective. One of the best techniques includes the ABCDE trick. This helps you a lot with prioritising tasks and is easy to do, “A" items are most important, "B" items only have minor consequences, "C" tasks have no consequences, "D" tasks can be delegated, and "E" tasks can be eliminated. Students can use this one to mark them from most important to least important and henceforth, spend more and more time on things that may have bigger impacts.

Body tube: It is the hollow tube at the upper arm, which has one end of the eyepiece lens, and another term has an objective lens. The body tube is altered using the adjustment knobs.
