The primary purpose of a telescope is toGroup of answer choicesmagnify distant objectsmeasure the brightness of stars very accuratelyseparate light into its component wavelengthscollect a large amount of light and bring it into focusmake distant objects appear nearby

What is the resolution of a telescope?Group of answer choicesits ability to distinguish two adjacent objects close together in the skyits ability to see very faint objectsits ability to make distant objects appear much closer to usits ability to focus more than just visible light for imagingits ability to separate light into its component colors for analysis
