What is telescope?

Posted by Shei****@***** 6 years ago

CBSE > Class 12 > Physics

1 answers

Adhimoolam Abirami 6 years ago

The telescope is used to provide angular magnification of distant objects. The objective has a large focal length and a much larger aperture than the eyepiece because object is very far away. Light from a distant object enters the objective and a real and inverted image is formed at its second focal point.
