What is a Refracting Telescope And Its Working

What is a Refracting Telescope?
The Refracting Telescope is the first type of Telescope invented. A Refracting Telescope is basically a type of an optical telescope (Telescope that gathers and focuses light), which makes use of a lens to form an image. A Refracting telescope is also know as a refractor telescope. Refracting or Refractor telescope focus the light and make distant objects brighter, clearer and even magnified. Refracting telescopes usually make use of two main lenses. The larger lens is known as the objective lens, and the smaller lens which is used for viewing objects is known as the eyepiece lens. These telescope were usually or basically designed to use in spy glasses and astronomical telescopes.
These type of telescopes are used to examine the visible-light region of the electromagnetic spectrum. The name refractor is derived from the word refraction, which is the bending of light when it passes from two different mediums of different density. For example - From Air to Glass.
These telescopes are typically used to examine the Moon or the other objects of the solar system such as the jupiter , Mars and even the binary stars.

How does a Refracting or Refractor Telescope works?
A Refracting Telescope works by bending light through a lens so that it forms and image. This telescope works just like a magnifying glass. It makes of a convex lens, to bend light and bring it into focus.

Two main problems with Refracting Telescope:

• Images are not always clear because the light is being bent.
• The size of the lens is limited which limits the power of the telescope. 

  
NOTE:-
Though the design of these telescopes has been improved over the years, the general technology remains the same.
