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, but with much lower sensitivity than a single, 100- kilometer telescope.
b. Yes, and the resulting interferometer will have exactly the same properties as a single, 100-kilometer telescope.
c. No, interferometry only works over much smaller distances.
d. No, the blurring effects of Earth’s atmosphere limit the achievable angular resolution.
Ans: a. Yes, but with much lower sensitivity than a single, 100- kilometer telescope.
