Explanation:
Detailed explanation-1: -Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the “Danish perspective glass” in 1609, Galileo constructed his own telescope. He subsequently demonstrated the telescope in Venice.
Detailed explanation-2: -He had a focus shift that adjusted the length of the telescope showing that he was aware of the optical power of lenses which he linked to their “lengths”. He also defined and calculated the apparent field of view of his telescope and used this to measure angular distances between celestial bodies.
