Draw a ray diagram of reflecting type telescope and hence give the advantage of reflecting type telescope.

Open in App

Solution

1. A pure reflecting telescope does not suffer from chromatic aberration. A lens, on the other hand, bends different colors of light at different angles.
2. Light bent by a reflector interacts with a single surface (the mirror).
3. Very large lenses are very heavy
