A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). There are many different types of telescope including radio, infrared, visual, X-ray and gamma ray. Each of these telescopes are use to detect its own certain type of electromagnetic light in space, all of which look very different.
Radio Telescope:
Radio telescopes are used to study naturally occurring radio emission from stars, galaxies, quasars, and other astronomical objects between wavelengths of about 10 meters and 1 millimetre. Radio telescopes vary widely, but they all have two basic components: (1) a large radio antenna and (2) a sensitive radiometer or radio receiver. Radio Telescopes are normally quite large so that they can receive long radio waves better.

Reflective
Telescope:
A reflecting telescope (also called a reflector) is an optical telescope which uses a single or combination of curved mirrors that reflect light and form an image. Reflectors are used not only to examine the visible region of the electromagnetic spectrum but also to explore both the shorter- and longer-wavelength regions adjacent to it (i.e., the ultraviolet and the infrared). Reflecting telescopes use curved mirrors instead of convex lenses to collect and focus light. A large concave mirror (the centre is thinner than the edges) collects and reflects the light to make an image. Once the image forms, the lens in the eyepiece magnifies the image.

Refractive
Telescopes:
A refracting telescope works just like a magnifying glass. It uses a convex glass lens to bend light and bring it into focus. This lens is thicker in the centre than it is toward its edges, which bends the light more at the edge of the lens than light coming through the centre. Both the refractive and reflecting telescopes are used to look up into space from Earth or from space down to Earth or other planetary objects.
