hi Caroline
The Lovell Telescope is a radio telescope at Jodrell bank (Cheshire U.K). It can observe wavelengths up to ~5 Ghz.
The Hubble Space telescope is a reflecting Telecope
Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.

An optical telescope.
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
The instrument scientists use to observe the planets is a high powered telescope.
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.

The word 'telescope' is a noun.Example: "I don't know how to use a telescope."
Perhaps you are thinking of a radio telescope, although your question is quite open-ended. Voltmeters, frequency counters, and trombones also fit the description.
