Astronomical telescope class 12 notes. Calculate the focal length of the objective and the eye piece. Galilean Telescopes ve Objective lens F o and -ve Eyelens F E The image produced by a Galilean Telescope is erect The exit pupil is formed inside the instrument The length of the Galilean Telescope is shorter than the Keplerian Specified by the magnification 2x 25x etc. The magnifying power of an astronomical telescope in the normal adjustment position is 100.

Class 12 Physics Ray Optics Optical Instruments. An optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum to create a magnified image for direct view or to make a photograph or to collect data through electronic image sensors. 2 FUNDAMENTALS 7 In radio astronomy nearly always hν.

A simplified explanation of the following terms have been provided under this section in Ray Optics And Optical Instruments Class 12 Notes. A reflecting telescope also called are flector is an optical telescope which uses a single or combination of curved mirrors that reflect light and form an image. -1 fo 100 fe -2 Substituting equation.

Physics Project Report on Astronomical Telescope. We have another article as well on types of telescopes. Now there are many different types of telescopes but the ones which we are going to deal with in class 12th are refracting telescopes.

Get important notes of CBSE Class 12th Physics on the chapter Ray Optics and Optical Instruments. 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.

Here is the link of that article if you want my personal notes of Ray Optics Notes cover all the topics of Ray Optics of class 12th including telescope Conclusion. Conclusion The astronomical telescope designed is able to produce real inverted and magnified images of the objects very far away from it. Using this we can make the approxima-tion.
