Explain the construction of Galileo’s telescope.

Answer»
  • The Galileo’s telescope is made up of two or more convex lenses. 
  • The lens facing the object is called the objective lens which is made as large as possible to collect the maximum amount of light coming from a heavenly object.
  • The lens closer to the eye is called the eyepiece which uses the light collected by the objective lens and produces a large image of the source.
  • Such a telescope is also called a refracting telescope.
