Magnification of telescope formula class 12. O distance of the object from the lens. These lenses have negligible thickness. Magnifying power of telescope.
This is the currently selected item. Download Handwritten Notes of Chapter 9 Physics Class 12th Download. Class 12 Physics Ray Optics Optical Instruments.
Then the magnification is f O f e 76225 3048 which we would just call 30. It is given as. Most of the topics are already covered in Part I and Part II.
Class 12 Physics Ray Optics Optical Instruments. There is no linear magnification hence the total angular magnification of the astronomical telescope when the eye focused at the far point or the accommodation is minimum M The total angular magnification of the ocular lens when the eye focused at the far point or the accommodation is minimum M ok. The objective has a large focal length and a much larger aperture than the.
Learn the concepts of Class 12 Physics Ray Optics and Optical Instruments with Videos and Stories. This is given by the famous Abbes criterion given by Ernst Abbe in 1873 as. Simple Microscope or Magnifying Glass.
Mathematically we can writewhere fo is the focal length of the objective fe is the focal length of the eye-piece and D is the least distance of distinct vision. Derive the formula for angular magnification of a compound microscope when the final image is formed at least distance of distinct vision. B Using the lens equation for objective lens Hence magnification due to the.
