A
the wavelength
B
the diameter of the objective
C
the diameter of the eye piece
D
the focal length of eye piece
Correct Answer
the diameter of the objective
Detailed Explanation
Resolving power of telescope is defined as the reciprocal of the smallest angular separation between two distant objects whose images are seen separately.
Resolving power of telescope RP=1.22λ
where
a is the diameter of objective lens of telescope.
RP ∝ a
Thus resolving power of telescope can be increased by increasing the diameter of objective lens of telescope.
