Explain the construction of Galileo telescope

Answer 1

hey buddy here is u r answer⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩

The design Galileo Galilei used in 1609 is commonly called a Galilean telescope. 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

a Galileo telescope is defined as having one convex lens and one concave lens. the concave lens serves as the ocular lens, or the eyepiece, while the convex lens serves as the objective. The lens are situated on either side of a tube such that the focal point of the ocular lens is the same as the focal point for the objective lens.
