Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Also, ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.

What type of telescope does not use visual light energy?

Radio telescopes do not use visual light energy. Instead, they detect radio waves emitted by celestial objects in space. These telescopes are used to study various astronomical phenomena, such as pulsars and galaxies.


What telescope doesn't use visual light?

Scientists have developed a number of radio, infrared, ultraviolet, and X-ray telescopes.


Do telescopes use energy?

Yes. It takes energy to move them in the correct direction. In home telescopes, this is done by hand (energy from your muscles), in large telescopes they use some kind of motors to do that.


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.


How do telescopes for invisible wavelengths differ from those for visible light?

Visible Light telescopes use mirrors or lenses. The images are viewed by the naked eye. Telescopes operating in invisible wavelengths use Electromagnetic sensors. The data is then converted into an image that can be viewed by us.

What are the tools scientist use observe objects in the night sky?

Scientists use telescopes, such as optical telescopes, radio telescopes, and space telescopes, to observe objects in the night sky. They also use instruments like spectrographs and cameras to analyze the light from celestial objects and gather data for research and study.
