Which of the following statements best describes the two principle advantages of telescopes over eyes? a. telescopes have much more magnification and better angular resolution. b. telescopes can collect far more light with far better angular resolution. c. telescopes can collect far more light with far greater magnification. d. telescopes collect more light and are unaffected by twinkling

Answer;

B. Telescopes can collect far more light with far better angular resolution.

Explanation;The angular resolution is the angular size of the smallest features that the telescope can see, which means a smaller angular resolution is better.The angular resolution of an optical telescope is determined by the diameter of the primary mirror or lens gathering the light. The angular resolution of a telescope is better compared to that of the eye (which is about 1 arcminute, or 1/60 of a degree )Human eye functions like a telescope, but with a very small aperture and therefore can gather a very limited amount of light from faint objects. This makes telescopes advantageous as they can gather more lightand can also distinguish two objects at a greater distance as compared to the human eye.
