A) increase the resolving power of the telescope
B) increase the magnifying power of the telescope
C) to focus on distant objects
D) make image aberration less
Correct Answer: A
Solution :
Resolving power of the telescope is \[=\frac{a}{1.22\lambda }\] where a = diameter of aperture of objective lens \[\lambda \]= wavelength of light Therefore, resolving power \[\propto a\] As aperture of the objective lens increases, resolving power of telescope increases.You need to login to perform this action.
