Who is credited with inventing the reflecting telescope?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Isaac Newton.
Sir Isaac Newton is widely credited with inventing the first practical reflecting telescope in 1668.1 He devised this revolutionary design to overcome the chromatic aberration (color distortion) inherent in the refracting telescopes of his time, which used lenses.2 Newton's design utilized a concave mirror to collect and focus light, along with a smaller flat mirror to direct the image to an eyepiece on the side.3 This innovation marked a significant leap in telescope technology and laid the foundation for future, larger, and more powerful astronomical instruments.4
