Study the figure and answer the following questions
a. What type of telescope is shown in the figure?
b. Label the main parts of the telescope.
c. Which type of mirror does the telescope use?
d. What other type of telescope uses a curved mirror?
e. Explain the working of the above telescope.
Answers
Here is your answer:-
a. ans:-The telescope shown in the figure is the Newtonian reflecting telescope.
b. ans:-The main parts used in the telescope are:-
1- The Tube assembly: This is the long white part and it holds the mirror, the secondary mirror, the eyepiece and holder. It is the whole optic system.
2- The Mount assembly: This is the whole assembly that supports and moves the telescope tube.
3- The eyepiece assembly: There is a knob for focusing and a sleeve that you can insert various sized eyepieces in.
4- Hidden inside the tube at this end is the primary mirror that gathers all the light and reflects it back up toward the eyepiece
5 - The counterweight: This is a heavy weight (black) that can be slid up and down on the silver bar to balance out the telescope and make it very easy to maneuver.
6- The Motor: Not all reflector telescopes have this but it is a motor that turns the telescope (It's the big black object). The motor rotates 1 complete revolution every 24 hours and what this does is allow you to point the telescope at an object and then with the motor on it will automatically follow the object across the sky.
c. ans:-The Newtonian reflecting telescope uses a concave mirror.
d. ans:-Other than the Newtonian reflecting telescope, astronomical reflecting telescope uses a curved mirror.
e. ans:- It works as follows:-
Instead of using a lens to gather light, Newton used a curved, metal mirror (primary mirror) to collect the light and reflect it to a focus. Mirrors do not have the chromatic aberration problems that lenses do. Newton placed the primary mirror in the back of the tube.
Hope it helps you!!
