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.
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.
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!
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.
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.

What is the difference between a mirage and an optical illusion?
All mirages are optical illusions but all optical illusions are not mirages.
Optical telescopes are designed to collect and create images from is it white or visible light or x rays or infrared radiation or gamma rays?
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.
What is the difference between Optical Zoom and Digital Zoom for a digital camera?
A optical zoom use the lenses to focus in on a subject, pretty much the same way binoculars work. Digital zoom magnifies the subject by enlarging in in the pic thru a digital process, this is not a true type of zoom.
Do people see optical illusions the same way?
No matter what hand you do task with doesn't make a difference in the way you see optical illusions.
What are good questions to ask about optical illusions?
Questions asked about optical illusions; 1: What are optical illusions? 2: What types of optical illusions are there? 3: What effects do optical illusions have on the brain 4: What causes optical illusions?
What is the difference between optical and radio?
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
In what ways are radio telescopes better than optical telescopes?
Radio telescopes can observe objects that are not visible in optical light, such as cold interstellar gas clouds. They are also able to penetrate through dust and gas that can block optical light. Radio telescopes can provide information about different physical phenomena, such as synchrotron radiation from high-energy particles or cosmic microwave background radiation.
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
Do Optical telescopes have poorer resolution than radio telescopes?
Not necessarily.
How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Are radio telescopes detect objects that optical telescopes cannot?
Yes, that is correct.
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What is catadioptric telescope?
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.
What limits the power of an optical telescopes?
aperture
What do Optical telescopes gather?
beams of light
What other kinds of radiation are detected by telescopes?
Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes
