Can you recommend a good site that explains why we use filters to observe the Sun in different wavelengths,and why the outer part of the Sun (Corona)is hotter than the inner parts.
Certainly! If you're looking for a good site that explains why we use filters to observe the Sun in different wavelengths, and why the outer part of the Sun (Corona) is hotter than the inner parts, I would recommend starting with the following steps:
1. Visit NASA's official website (www.nasa.gov) or the European Space Agency's official website (www.esa.int) - these organizations provide reliable and accurate information related to space and astronomy.
2. In the search bar of the website, type in keywords such as "Sun observations" or "Solar filters." This will help you find articles, resources, or pages related to solar observations and the use of filters.
3. Look for articles or sections specifically discussing solar observations or the Sun's atmosphere, including the corona. These sections often provide explanations for why different wavelengths and filters are used to study the Sun.
4. Explore the information provided, paying attention to details on how filters work to observe different regions of the Sun and why studying the Sun's corona is important. Look for sections that discuss the mechanisms behind these phenomena.
5. As you read through the articles or sections, make sure to take note of any important concepts, observations, or theories mentioned. These will help you understand why filters are necessary and why the corona is hotter than the inner parts of the Sun.
By following these steps, you should be able to find reliable and comprehensive information on why filters are used for solar observations and why the Sun's corona is hotter than its inner regions. Remember to always rely on reputable sources for accurate scientific explanations.
