Question
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.
