Task · part of 3. Telescopes and binoculars: four explanations, with diagrams
3(b). Several types of telescope compared, including one beyond visible light
Required Often forgotten
Similarities and differences, and at least one that observes outside the visible spectrum: radio, X-ray, ultraviolet or infrared. That one is the part people forget.
Notes and warnings
Note. At least one of the telescopes compared has to observe light beyond the visible part of the spectrum: radio, X-ray, ultraviolet or infrared. It is the clause people skim past, and it is the one that turns this into a real comparison rather than a list of refractors and reflectors.
