Need Ideas for a Physics Extended Essay for IB

[wjwhs010101]

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.
