Courses Need Ideas for a Physics Extended Essay for IB

AI Thread Summary
The discussion centers on two potential research topics: the role of mirrors in space telescopes and the efficiency of optical fibers in transmitting light. The first topic involves investigating how the shape and coating of mirrors influence their focal properties and light reflection efficiency, with a specific focus on comparing the designs of the Hubble Space Telescope and the James Webb Space Telescope (JWST). Suggestions for a lab exercise include combining images from multiple mirrors to explore related challenges. The second topic examines how imperfections in optical fibers impact total internal reflection and overall light transmission efficiency. Concerns are raised about the feasibility of conducting experiments related to the first topic in a high school lab setting, prompting a request for practical ideas.

I have researched some topics, but I am not sure what to do.

The topics that I found are:
Topic: The Role of Mirrors in Space Telescopes
Research Question: How do the shape and coating of mirrors affect their focal properties and light reflection efficiency?

Topic: The efficiency of optical fibers in transmitting light.
Research Question: How do imperfections in optical fibers affect the total internal reflection and efficiency of light transmission?

I was thinking about doing the first one, but I'm not sure if I will be able to conduct the experiment in a highschool lab environment. Please give me ideas, and I will genuinely appreciate it!

Compare and Contrast the designs of the Hubble and JWST. What is different about their mirrors? Why are they like that? For your lab exercise, you could try combining multiple images from multiple mirrors into one and explore the issues with doing that. :smile:
 
I’ve been looking through the curricula of several European theoretical/mathematical physics MSc programs (ETH, Oxford, Cambridge, LMU, ENS Paris, etc), and I’m struck by how little emphasis they place on advanced fundamental courses. Nearly everything seems to be research-adjacent: string theory, quantum field theory, quantum optics, cosmology, soft matter physics, black hole radiation, etc. What I don’t see are the kinds of “second-pass fundamentals” I was hoping for, things like...
I graduated with a BSc in Physics in 2020. Since there were limited opportunities in my country (mostly teaching), I decided to improve my programming skills and began working in IT, first as a software engineer and later as a quality assurance engineer, where I’ve now spent about 3 years. While this career path has provided financial stability, I’ve realized that my excitement and passion aren’t really there, unlike what I felt when studying or doing research in physics. Working in IT...
