A telescope has been adjusted for relaxed eye. You are asked to adjust it for least distance of distinct vision, then how will you change the distance between two lenses?

For relaxed eye, `L = f_0 + f_e`
for least distance of distinct vision
` L' = f_0 + u_e, u_e lt f_e`
Therefore, L' < L, that is, the distance will be decreased.

The focal length of the objective of an astronomical telescope is 75 cm and that of the eyepiece is 5 cm . If the final image is formed at the least distance of distanct of distinct vision from the eye, calculate the magnifying power of the telescope.

A compound microscope has a magnification of 30. The focal length of eye piece is 5 cm. Assuming the final image to be at least distance of distinct vision, find the magnification . produced by the objective.

A compound microscope consists of an objective lens of focal length 2.0 cm and an eyepiece of focal length 6.25 cm separated by a distance of 15 cm. How far from the objective should an object be placed in order to obtain the final image at (a) the least distance of distinct vision (25cm), and (b) at infinity? What is the magnifying power of the microscope in each case ?
