Question

The final image formed by an astronomical telescope is
A.Real and erect
B.Virtual and erect
C.Real and inverted
D.Virtual and inverted

Answer 1

There are different types of telescopes. An astronomical telescope is an optical device or instrument that is used to observe the magnified image of distant heavenly bodies. By understanding the above information about astronomical telescope analyze the characteristics of the image (real, inverted, erected, virtual etc)

Complete answer:
The astronomical telescope is used by the astronauts to observe the far and distant objects in a magnified way.
The distance of the object and the observer will be very large. The telescope will magnify the image of the object which can be observed in the telescope. Hence one of the characteristics of the image is magnified.
Due to the fact that the image is magnified it is inverted, we can observe the magnified images only they get inverted in most of the cases and we can only see the virtual image of the object.
Hence the final image formed by an astronomical telescope is virtual, magnified and inverted.

Therefore the option (D) is the correct answer.

Note:
There are different types of optical objects through which we can observe images of different types of objects with different distances. According to their use and characteristics of the image they are classified, for example telescope, astronomical telescope, compound microscope etc are some of the optical objects of this type.
