As you'll learn in the next module, astronomers use lots of different kinds of telescopes that work at different wavelengths across the EM spectrum. We have optical telescopes, like the Hubble, but also radio telescopes, infrared telescopes, UV telescopes, X-ray telescopes, etc. Say you wanted to study brown dwarfs - stellar-like objects that are a bit smaller and cooler than "regular" stars (we'll learn more about these later on in the course). Brown dwarf surface temperatures average around 1000K. What type of telescope should you use? i. e. what wavelength range should it operate at to have the best chance of detecting these types of stars? Explain your reasoning clearly and show your work.
