State the difference between optical and non-optical telescopes?

Answer 1

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.

Answer 2

an optical telescope only detcts visible light and sends it to an eyepiece for you to look through or attatch a camera. nonoptical telescopes sense other things on the radiometric spectrum, like: radio waves, gamma rays, infared, ultraviolet waves, ect; and sends them to a computor. COBE, for example is a nonoptical telescope. it detects background radiation from the big bang.

Answer 3

We can "see" stuff we would not be able to see with our own eyes (like radio waves). This helps us to see some stars or other objects in space more vividly (like see a black hole emitting large amounts of microwaves which is not visible to our eyes). It's like seeing in a different way. Hope I helped!

Answer 4

A telescope may be both, but not necessarily. Refracting means that it uses refraction, that is, lenses. That may be for visible light, or for other types of radiation, for example, radio waves or x-rays. Optical means that it works with visible light. In that case, it may use lenses, or mirrors (reflecting). In principle, all four combinations are possible: refracting / visible light, refracting / other radiations, reflecting / visible light, reflecting / other radiations.

Answer 5

A radio telescope IS a reflecting telescope.

The structure and physical dimensions of a telescope with given performance characteristics

depends on the wavelengths you want it to work with. All of the differences that you notice

between optical telescopes and radio telescopes are results of the fact that radio telescopes

are designed and constructed for the purpose of collecting, focusing, and detecting electromagnetic

radiation whose wavelengths are more than a million times longer than the other kind.
