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.
a cylinder-shaped device for making objects that are far away look closer and larger, using a combination of lenses, or lenses and curved mirrors. /GettyImages. Examples. With a good telescope, you can see craters on the moon. A low-power telescope is enough if you only want to look at the moon. I used a pile of books as a rest for my telescope.
Nowadays, the word "telescope" is defined as a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century.
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.
Jul 11, 2024 · Telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
A telescope is an instrument that is used to view distant objects. If you want to look at the planets, you can use a telescope. The higher the magnification on the telescope, the better your view will be.
tel•e•scope. 1. an optical instrument for making distant objects appear larger and nearer when viewed directly through lenses ( refracting telescope) or indirectly as through images focused by a concave mirror ( reflecting telescope ). 2. consisting of parts that slide one within another.
