Light and optics/Telescopes

Editable telescopeEdit

 
Editable refracting telescope Though crude looking, this can be edited to create very precise ray diagrams. The rays can be first made very thin to align everything to a fraction of a pixel.

Searching commonsEdit

These ray diagrams were selected because they

  1. are editable svg files
  2. should be converted to svg because the usefully explain how to draw ray diagrams
  3. have historical interest
  4. describe refracting telescopes (do reflectors later)
