Open in App
Solution
The correct option is A Newtonian
The telescope given in the figure is a Newtonian telescope, which is a reflecting kind of telescope where light rays coming from the object are reflected by a concave mirror. Before the reflected rays converge at the focus, they are deflected by a small plane mirror, and are then focused at a point lying perpendicular to the axis of the telescope. The rays then pass through the eyepiece and a magnified image is formed.
