write short notes on the cassegrain telescope
Answers
Answer:
The Cassegrain telescope is an astronomical reflecting telescope, in which the light is incident on a large concave paraboloid mirror, and reflected onto a smaller convex hyperboloid mirror. This reflected light is reflected again through a hole in the concave mirror to finally form the image.

The reflecting principle used in the working of this telescope is incorporated in most modern optical telescopes. This telescope was invented by a Frenchman named Nicolas Cassegrain. Cassegrain designs are also used in the construction of satellite communication systems, such as earth stations and radio telescopes.
