A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. [1] . Originally it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope.
The meaning of TELESCOPE is a usually tubular optical instrument for viewing distant objects by means of the refraction of light rays through a lens or the reflection of light rays by a concave mirror. How to use telescope in a sentence.

Jun 13, 2024 · A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The first telescopes focused light by using pieces of curved, clear glass, called lenses. So why do we use mirrors today?

telescope. / tĕl ′ ĭ-skōp′ / An arrangement of lenses, mirrors, or both that collects visible light, allowing direct observation or photographic recording of distant objects. A refracting telescope uses lenses to focus light to produce a magnified image. Compound lenses are used to avoid distortions such as spherical and chromatic aberrations.
An optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors . There are three primary types of optical telescope:
Telescopes Astronomers observe distant cosmic objects using telescopes that employ mirrors and lenses to gather and focus light. The size of the main mirror or lens determines how well a telescope can collect light. The larger a mirror or lens, the more light it collects, and the better its ability to detect fainter objects. Refracting […]
May 28, 2008 · A telescope is an instrument designed to collect electromagnetic radiation (light) for the observation of remote objects. The word “telescope” comes from the Greek words tele =far and skopein =to look or see. The first known telescope was built by the Dutch lens-maker Hans Lippershey in 1608.
