Problem
Explain in one or two sentences why increasing the diameter of the objective of an astronomical telescope improves its resolving power.Intuitive explanation
A larger objective lens collects more light and has a longer effective wavelength baseline, both of which allow it to distinguish finer angular details between distant objects. The key insight is that resolution depends on the ratio —smaller wavelength-to-diameter ratios mean sharper separation of closely spaced stars.
