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.

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.
How are pinhole cameras and electromagnetic waves relate to each other?
All types of cameras, pinhole and those using optical lenses, use light which is an electromagnetic radiation
How does refraction cause an optical illusion please answer?
Optics is the study of how light (moreso Electromagnetic Radiation) travel and interact with objects (solid state physics, electrodynamics etc.). Optical illusions deal with how light is interpreted by the human brain. So optics studies how light gets to the eye, optical illusion is about how the brain perceives that light.
What are the tricks used in optical illusions?
Most optical illusions mess with your natural inclination to predict things - our brain thinks they are moving, so tries to estimate how far the will travel. Others simply work around our senses being designed for 3D while displaying 2D images.
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 does a specialized non-optical telescope see?
There are telescopes used to detect radio waves and others to detect infrared radiation.
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
Optical telescopes are designed to collect and create images from?
mirrors and/or lenses
In what ways are radio telescopes better than optical telescopes?
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
Do digital telescopes exist?
No, digital telescopes don't exist. The telescope which we know are optical telescopes and what NASA uses are radiation based telescopes, or something related to radioactivity. As far I know, I've never heard about digital telescopes.
How do scientist study invisible radiation from objects in space?
They study visible light by using optical telescopes.
Why are reflecting and fefracting telescopes classified as optical telescopes?
"Optical" simply means that they work with visible light - as opposed to other EM radiation (radio waves, x-rays, etc.); gravitational waves; etc.
What are the types of telescopes that are used for astronomical observation?
The three major types are the optical, the infrared, and the radio telescopes. There are other specialized instruments for observing gamma rays, or x-rays, or for doing processes such as interferometry. Among the optical telescopes are the refracting (lens), reflecting (mirror) and compound telescopes (computer-assisted combinations of several smaller telescopes to simulate a much larger one).
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Why do single dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter?
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
What are examples of non-optical telescopes?
All types of lens that see parts of the electromagnetic spectrum other than light. E.g. infrared cameras
