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.
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 the Uses of reflecting light?
Mirrors and telescopes use light reflection.
Do refracting and reflecting telescopes use visible light to view the images?
Those terms are most commonly used for optical telescopes. However, the same design can be used for non-visible frequencies; for example, radio telescopes of the "satellite dish" variety are essentially reflecting telescopes.
How might the Hubble Space Telescope change today's model of the solar system?
Because we still use telescopes today, and it helped us build a more & new advanced telescope today
What items do they use in space that they use on earth?
Optical and Radio telescopes.
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
What are the largest telescopes used for observations in the visible region of the spectrum?
The largest telescopes that use visible light are reflector telescopes.
What are the largest telescopes used for observations in the visible region of the spectrum called?
The largest telescopes that use visible light are reflector telescopes.
How do optical radio telescopes operate?
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
What type of telescopes use the visible spectrum to see the universe?
An optical telescope.
What design variants might one see in an optical telescope?
Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.
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

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.
What type of optical telescopes use mirrors to focus light?
concave mirrors, and curved mirrors
Why do you use telescopes today?
to enjoy the beauty of the stars.
What can radio telescopes do that optical telescopes cant?
No. The gain of the antenna ... which translates directly into angular resolution ... depends on the wavelength (frequency) of operation.The 2.5 meter optical parabolic reflector (telescope) on Mt. Wilson is a titan. 2.5 meter parabolic radio antennas are routinely used in intercity microwave communication but would be quite useless for serious radio-astronomy, as they are such shrimps at radio wavelengths.
