This download is a PowerPoint and lesson plan explaining the limitations of non-optical telescopes due to resolving power and the Rayleigh Criterion. Included is a simple practical idea for testing the resolving power of the human eye.
This is lesson 4 / 12 from my Astrophysics / Cosmology course, all available individually or as a bundle at a reduced price.
Similarities and differences of radio telescopes compared to optical telescopes. Discussion should include structure, positioning and use, together with comparisons of resolving and collecting powers.
Minimum angular resolution of telescope.
Rayleigh criterion and formula
Collecting power is proportional to diameter ^2
Students should be familiar with the rad as the unit of angle.
