You need special optics to focus infra-red.

The longer wavelengths do not focus at the same point (they are bent less by refraction).

Mirror optics are better.

How is a radio telescope similar to a refracting telescope and a reflecting telescope?

Radio telescopes, refracting telescopes, and reflecting telescopes all use mirrors or lenses to collect and focus incoming electromagnetic radiation. The main difference is the wavelength of the radiation they are designed to study – radio telescopes focus on radio waves, refracting telescopes focus on visible light, and reflecting telescopes focus on a variety of wavelengths including visible light, ultraviolet, and infrared.


What element focuses infrared radiation?

nothing Anything that is transparent will have a refractive index. Glass is transparent to visible light and has a refractive index with it. Having these combined properties lets you make a lens for visible light out of glass. Now glass is transparent to IR radiation so any glass lens would focus IR radiation.


A telescope collects electromagnetic radiation from outer space and does what to it?

Yes a telescope collects electromagnetic radiation (light) an then brings this light to a focus so that the source of the light is magnified. The larger the diameter of the telescope, the more light it collects making the image at the focus brighter so as well as magnifying the image a telescope also allows one to see fainter objects.


How is an optical telescope different from the others?

An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.


What is an artificial telescope?

An artificial telescope refers to a telescope that is man-made and not naturally occurring. They are designed to collect and focus light from distant objects for observation and study. Artificial telescopes can be found in various forms, including optical, radio, x-ray, and infrared telescopes.


What is the wavelength of a infrared telescope?

Visible light is about 350-700 nm, so infrared radiation would have a wavelengt above 700 nm (0.7 microns), approximately. It is not a single wavelength, but a wide range of wavelengths. The upper range is about 300 microns. Wavelengths above that are called microwaves.


What does a telescope focus and collect from space for closer observation?

it gather electro magnetic radiation from object in space and concern trites it for better observation


What is the advantage of having telescope that collect and focus radiation?

All telescopes collect or focus radiation in some way, because visible light is a form of electromagnetic radiation. The advantages of telescopes include being able to see things that are far away, as well as the ability to observe heavenly bodies.


What type of telescope minimizes color focus problems?

A telescope with achromatic lenses.


This telescope uses mirrors to gather and focus light energy?

Newtonian telescope


What do you call a telescope that uses a lens to focus light?

It is called a refracting telescope.


Does the Hubble Telescope use mirrors or lenses to focus the image?

The Hubble Telescope uses both mirrors and lenses to focus on images.
