Draw a schematic ray diagram of reflecting telescope showing how rays coming from a distant object are received at the eye-piece. Write its two important advantages over a refracting telescope.

The diagram for the schematics ray diagram of the reflecting telescope is

In the reflecting telescope, the image that is formed by the back reflection from a curved surface, is magnified or gigantified by the second mirror.

The advantages of reflecting telescope is

1. There is no deviation for the reflecting telescope as the objective is kept is a mirror.

2. Spherical deviation is lowered when it comes to reflecting telescope by using mirror objectives is a mode that shapes like a parabolic.
