An astronomical refracting telescope is being used by an observer to observe planets in normal adjustment. The focal lengths of the objective and eye piece used in the construction of the telescope are $\displaystyle 20$ m and $\displaystyle 2$ cm respectively. Consider the following statements about the telescope :
(a)
The distance between the objective and eye piece is $\displaystyle 20.02$ m
(b)
The magnification of the telescope is (-) $\displaystyle 1000$
(c)
The image of the planet is erect and diminished
(d)
The aperture of eye piece is smaller than that of objective
The correct statements are :
Official answer
(1)
(a), (b) and (d)
