When was the day Sir Isaac Newton made the reflecting telescope?

Answer 1

Newton did not invent the telescope. The first practical telescope was made by Hans Lippeshey and Zacharias Janssen in 1608 in the Netherlands. Galileo made significant improvements the following year. All these early refracting telescopes suffered from big problems with chromatic aberation, the separation of colours.

The first reflecting telescope is credited to Niccolò Zucchi in 1616. In 1668, Isaac newton invented a much improved reflecting telescope that still bears his name, the "Newtonian reflector." He added a smaller "diagonal" mirror near the primary mirror's focus to reflect the image at a 90° angle allowing him to look through the side of the telescope and see without blocking the incoming light.

Nice answer upstairs! Newton made his first "good" reflecting telescope in 1688. It still exists -- and works!

Answer 2

Isaac Newton invented a reflecting telescope while teaching at Trinity College, Cambridge, England. {Roughly, sometime during the winter of 1667-1668.}

Note that telescopes had been used for many years prior to this; those used prisms and lenses while Newton's invention dealt with mirrors. Newton did not invent "telescopes" but invented a new design of telescope.

Also note that Scottish mathematician James Gregory proposed the idea of a reflecting telescope three years earlier than Newton, but Newton was the first to build a working model. Newton's design was sufficiently different from Gregory's that Newton received acclaim for the concept.

Answer 3

Newton did not originally invent the telescope. They were invented in the Netherlands in 1608 and improved on by Galileo in 1609. Those were what are known as "refracting" telescopes (a series of lenses that the observer looks through). But Newton did invent the reflecting telescope, which uses a parabolic mirror to gather light, rather than a lens. The worlds largest optical telescopes are all reflectors.

Answer 4

yes isaac newton invented the reflecting telescope

Answer 5

Sir Isaac Newton built his first reflecting telescope in 1668!

Answer 6

During the mid 1660s Isaac Newton had his first reflecting telescope. Other scientists has experimented or proposed the design earlier.

Answer 7

No he didn't he only made an improved version of it.

Answer 8

Sir Isaac Newton made the reflection of the telescope on the 29th of October 1780s

Answer 9

he invented it in 1669 x

Answer 10

He wasn't born until 1642.
