ASTR209 - Lecture 12
In this lecture (back from illness, reading week, and the midterm exam!) we talk about "seeing", different telescopes, why we go to high altitudes to build them, and why we build telescopes to operate at different wavelengths (i.e. what different physical phenomena in the Universe emit at different wavelengths). We also begin to talk about radio telescopes.
