Question

What is the mechanism behind Newtonian telescope?

Answer 1

The Newtonian telescope is a type of reflecting telescope invented by the British scientist Sir Isaac Newton(1642–1727), using a concave primary mirror and a flat diagonal secondary mirror. Newton’s first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope.[1] The Newtonian telescope's simple design makes it very popular with amateur telescope makers.[2]

$\Large\bold\star\underline{\underline\textbf{Construction\:}}$

→ lt consists of metallic tube whose one end is open. A concave mirror of large aperture is fitted at the other end of the metallic tube. A plane mirror is inclined at an angle 45° with the axis of the metallic tube. Light from the object after reflettion is seen through the eye piece fitted at one side of the metallic tube.

$\Large\bold\star\underline{\underline\textbf{Working\:}}$

→ Beam of the light from the distant object (say star) incident on the objective (concave mirror). After reflecting from the concave mirror, the beam of light falls on the plane mirror M. The inclined plane mirror deviates the beam of light and final image is formed in front of the eye piece. The image is magnified by the eye piece and an enlarged image is seen through it.
