2020 Online Astronomy Institute - Module 2: From Pinholes to Space Telescopes
Explore what pinhole viewers and giant telescopes have in common through using lenses to construct a basic model of a telescope. Optical systems - like eyes, cameras, microscopes and telescopes - use lenses (and sometimes mirrors) to collect light and form images of distant objects. What do all these optical systems have in common? Light has to enter some kind of “hole” first.
