In summary, when working on a difficult problem for hours, it is important to take breaks and break the problem into smaller parts. One can also use strategies such as brainstorming, seeking help from others, and utilizing trial and error. To determine if one is on the right track, they can step back and evaluate their progress or explain the problem to someone else. To prevent frustration, it is important to have a positive mindset and switch up approaches if needed. If still struggling after hours of work, it may be helpful to take a break and seek outside help from a peer or mentor.

I have been working on this problem for HOURS! PLease helpe me!

Homework Statement


The objective of a telescope has a focal length of 200 cm and its eye piece has a focal length of 1 cm. What is the magnification of this telescope when viewing an object at infinity??


Homework Equations





The Attempt at a Solution



I thought ...
M = Fo/Fe which would = 200 but the answer is 20! Why? Does infinity have something to do with it??

Hello,

Thank you for reaching out for help. I understand that you have been working on this problem for hours and are feeling frustrated. I am a scientist and I am here to assist you with your question.

To answer your question, the magnification of a telescope is determined by the ratio of its focal length and the focal length of its eyepiece. In this case, the focal length of the telescope is 200 cm and the focal length of the eyepiece is 1 cm. Therefore, the magnification is 200/1 = 200.

However, when viewing an object at infinity, the image formed by the objective lens is at its focal point, which is also the focal point of the eyepiece. This means that the image formed by the objective lens is located at the same position as the eyepiece. As a result, the magnification is determined by the ratio of the distance between the eyepiece and the image formed by the objective lens, which is equal to the focal length of the eyepiece.

Therefore, the magnification in this case would be 200 cm/1 cm = 200. This is equivalent to saying that the image formed by the objective lens is magnified 200 times when viewed through the eyepiece.

I hope this explanation helps. Please let me know if you have any further questions or if you need more clarification. Keep up the good work and don't hesitate to reach out for help when needed. Good luck with your studies!
 

1. How can I stay focused when working on a problem for hours?

In order to stay focused when working on a problem for hours, it is important to take breaks and step away from the problem for a few minutes. This will help to clear your mind and prevent burnout. You can also try breaking the problem into smaller, manageable chunks to make it feel less overwhelming.

2. What strategies can I use to solve a difficult problem?

There are several strategies you can use to solve a difficult problem. Some common techniques include brainstorming, breaking the problem into smaller parts, seeking help from others, and utilizing trial and error. It is important to find the strategy that works best for you and the specific problem you are trying to solve.

3. How do I know if I am on the right track when working on a problem for hours?

One way to determine if you are on the right track is to take a step back and evaluate your progress. You can also try explaining the problem and your thought process to someone else, as this can help you identify any gaps in your understanding. Additionally, if you are making progress and learning new information, then you are likely on the right track.

4. How can I prevent feeling frustrated when working on a problem for hours?

To prevent feeling frustrated, it is important to have a positive mindset and remind yourself that it is okay to take breaks and ask for help. It can also be helpful to switch up your approach and try a different strategy if you are feeling stuck. Remember to celebrate small victories and acknowledge the progress you have made, even if it is not the final solution.

5. What should I do if I am still struggling with a problem after hours of working on it?

If you are still struggling with a problem after hours of working on it, it may be time to take a break and revisit it later with a fresh perspective. You can also seek help from a peer or mentor who may have a different perspective or approach to the problem. Remember to stay persistent and keep trying, as it is through these struggles that we learn and grow as scientists.
