Hint: A telescope is an instrument using lenses, curved mirrors, or a mix of both to observe distant objects, or various devices want to watch distant objects by their emission, absorption, or reflection of electromagnetic radiation.
Complete answer: A telescope forms a real and highly diminished image. the important image produced is inverted; i.e., the very best and bottom are reversed. When an object is placed away from a converging lens than the focal length, the lens produces an inverted, real and enlarged image, relying on how close the thing is to the main target. Telescopes are visual tools utilized within the sector of astronomy that magnifies an image with the use of lenses and mirrors.
There are two primary classifications of telescopes, refracting telescopes and reflecting telescopes. -Refracting telescopes use lenses to collect and focus the sunshine. -one among the foremost common kinds of reflector is known as a Newtonian telescope. Reflecting telescopes are used more and more in astronomy because of their ability to determine much farther and much clearer.
Note:Telescope may be a device which uses two lenses, primary lens forms a real image and a secondary lens is used as a magnifier to make an enlarged reflection. When an object is placed farther from a converging lens than the focal length, the lens produces an inverted, real image and enlarged image, depending how close the thing is to the main target.
