Question

Explain the construction of Galileo telescope.

Answer 1

The design Galileo Galilei used in 1609 is commonly called a Galileantelescope. It used a convergent (plano-convex) objective lens and a divergent (plano-concave) eyepiece lens (Galileo, 1610). A Galilean telescope, because the design has no intermediary focus, results in a non-inverted and upright image.

Answer 2

Galileo made first telescope . Galilean 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 maximum amount of light coming from a heavenly object.

The lens closer to the eye is called eyepiece which uses the light collected by the objective lens and produces a large image of source .

Such a telescope is also called a refracting telescope..
