Triangular prism real-world object?
If you asking where you'd find them in the real world - Binoculars and telescopes are two examples.
State the difference between optical and non-optical telescopes?
Optical measures visible light, Radio measures electromagnetic radiation in that part of the spectrum corresponding to radio waves. Same with X-ray telescopes and x-rays. Optical is the kind you look through.
What instrument is used to see visibly?
There are several instruments that are used to enhance visibility. Examples are; Spectacles and contact lenses Telescopes Microscopes
Most telescopes are telescopes?
refracting
Is the design of radio telescopes very similar to the design of refracting telescopes?
no, reflecting telescopes.
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What are the major types of optical telescopes?
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).
Is refracting telescopes bigger then reflecting telescopes?
No
