Question

Does this make sense: Thanks to interferometry, a properly spaced set of 10-meter radio telescopes can achieve the angular resolution of a single 100-kilometer radio telescope.

a. Yes
b. No
c. Depends on the principles of interferometry
d. Unsure

Answer 1

Yes, this statement makes sense. Interferometry is a technique used in radio astronomy that allows multiple radio telescopes to work together as a single instrument, increasing the resolving power and achieving higher angular resolution.

Step-by-step explanation:

Yes, this statement makes sense. Interferometry is a technique used in radio astronomy that allows multiple radio telescopes to work together as a single instrument, increasing the resolving power and achieving higher angular resolution. By linking properly spaced 10-meter radio telescopes, they can effectively simulate a single 100-kilometer radio telescope. This is because the resolution of an interferometer depends on the separation of the telescopes, not their individual sizes. The use of interferometry in radio astronomy has significantly improved our ability to observe and study distant objects in the universe.
