GENERAL KNOWLEDGE

Detailed explanation-1: -Ans – An astronomical telescope mainly has two lenses. The objective lens is used to form images of distant objects, while the eyepiece works as a magnifier to magnify the image produced by the objective.

Detailed explanation-2: -The earliest telescopes, as well as many amateur telescopes today, use lenses to gather more light than the human eye could collect on its own. They focus the light and make distant objects appear brighter, clearer and magnified. This type of telescope is called a refracting telescope.

Detailed explanation-3: -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.
