Telescope A has a mirror that is 10 times larger than the mirror of telescope B.Telescope A can resolve an angle as small as 0.1 seconds of arc.
What is the smallest angle that can be resolved by telescope B?
A)10 seconds of arc
B)1 second of arc
C)0.1 second of arc
D)0.01 second of arc

Question

Quizplus · Accepted Answer

The resolving power of a telescope is inversely proportional to the diameter of its mirror. If Telescope A has a mirror 10 times larger than Telescope B and can resolve 0.1 seconds of arc, then Telescope B, with a mirror 10 times smaller, can resolve an angle 10 times larger, which is 1 second of arc.
