A telescope has been adjusted for relaxed eye. How will you change the distance between objective lens and eye if final image is to be seen at the least distance of distinct vision ?
Text Solution

For relaxed eye, `l = f_(0) + f_(e)`(normal adjustment) To from the image at the least distance if distinct vision, `L' = f_(0) + u_(e) and u_(e) lt f_(e)`. `:. L' lt L`. Hence the distance between objective and eye piece has to be reduced.

For a normal eye, the least distance of distinct vision is
In a compound microscope, the distance between objective lens and eye lens is.
What is the distance between objective and eye lens of telescope in normal adjustment ?
What is the least distance of distinct vision for a normal human eye ?
Find the magnifying power of a compound microscope whose objective has a focal power of 100D and eye piece has a focal power of 16D when the object is placed at a distance of 1.1cm from the objective. Assume that the final image is formed at the least distance of distinct vision (25cm)
The total magnification produced by a compound microscope is 20 . The magnification produced by the eye piece is 5 . The microscope is focussed on a certain object. The distance between the objective and eye piece is observed to be 14 cm . If least distance of distinct vision is 20 cm , calculate the focal length of objective and eye piece.
(a) Draw a labelled ray diagram showing the formation of a final image by a compound microscope at least distance of distinct vision. (b) The total magnification produced by a compound microscope is 20. The magnification produced by the piece is 5. The microscope is focused on a certain object. The distance between the objective and eyepiece is observed to be 14cm. If least distance of distinct vision is 20cm, calculate the focal length of the objective and the eye piece.
In normal adjusment of telescope, final image is……. . And distance between objective lens and eye lens is………. .
