An astronomical refracting telescope will have large angular magnification and high angular resolution, when it has an objective lens of
asmall focal length and large diameter
blarge focal length and small diameter
clarge focal length and large diameter
dsmall focal length and small diameter.
✓ Correct answer: c) large focal length and large diameter
ExplanationThis contributes to high angular magnification, as a longer focal length lens bends light more, creating a larger image for a given object size.
