Using the data given below, state as to which of the given lenses will you prefer to use as (i) an eye-piece and (ii) an objective to construct an astronomical telescope? Give reason for your answer.

Four double convex lenses with following specifications are available Which of the given four lenses should be selected as objective and eyepiece respectively to construct an astronomical telescope?

The magnifying power of a telescope depends on the focal length of the objective and that of the eye- piece. Data of some lenses are given in the table. Choose any two lenses which are to be preferred as objective and eye-piece to construct a telescope. Give reason for your selection.

Four double convex lenses with following specifications are available Lens, A, B, C, D, focal length, 100 cm, 100 cm, 0 cm, 5 cm, aperture, 10 cm, 5 cm,2 cm, 2 cm. Which of the given four lenses should be selected as objected and eyepiece to construct an astronomical telescope and why ? What will be the magnifying power and length of the tube of the telescope ?
