A telescope, when in normal adjustment, has a magnifying power of 6 and the objective and eye-piece are 14 cm apart. The focal lengths of the eye-piece and the objective, respectively,

In normal adjustment, the length and magnifying power of an astronomical telescope are 80 cm and 15 respectively. What are the focal lengths of the objective and the eyepiece ?

An astronomical telescope arranged for normal adjustment has a magnification of 6. If the length of the telescope is 35cm, then the focal lengths of objective and euye piece respectivley =, are

The magnifying power of an astronomical telescope in the normal adjustment position is 100 . The distance between the objective and eye piece is 101 cm . Calculate the focal lengths of objective and eye piece.

An astronomical telescope has a magnifying power 10. The focal length of the eye piece is 20 cm. the focal length of the objective is -

An astronomical telescope has a magnifying power of 10 . In normal adjustment, distance between the objective and eye piece is 22 cm calculate focal length of objective lens.

An astronomical telescope has a magnifying power of 10 . In normal adjustment, distance between the objective and eye piece is 22 cm . The focal length of objective lens is.

The magnifying power of an astronomical telescope is 5 . When it is set for normal adjustment, the distance between the two lenses is 24 cm . Calculate the focal lengths of eye piece and objective lens.
