What type of telescope is shown in a diagram?
a. ans:-The telescope shown in the figure is the Newtonian reflecting telescope.
What are the 2 main types of telescopes?
There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope.
What is the difference between an astronomical telescope and a terrestrial telescope?
(i) Astronomical telescopes are used for viewing distant stars and planets whereas terrestrial telescopes are used for viewing distant objects on earth. (ii) The final image in the astronomical telescope is inverted whereas that in the terrestrial telescope is erect.
What is best type of telescope?
A reflector telescope is said to be the best value for your money, as they offer the most aperture for your dollar. For example, a 6-inch diameter refractor telescope can cost up to 10X as much as a 6-inch Newtonian reflector.
How does a Newtonian telescope work?
Newton’s idea was to install a flat reflecting mirror into the telescope tube. Light would first enter the top of the telescope tube. At the lower end, there is a primary mirror that is either spherical or parabolic in configuration. This mirror reflects the light upwards.
What are the types of telescope use a curved mirror?
A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image.
Which type of telescope is best?
What is the difference between astronomical telescope and Galilean telescope?
To reiterate: Telescopes come in two basic flavors—those with a high plus eyepiece lens, and those with a high minus eyepiece lens. High-plus-eyepiece telescopes are called astronomical (or Keplerian) telescopes; and high-minus-eyepiece telescopes are called Galilean (or terrestrial) telescopes.
