Which of the following greatly improves the angular resolution of radio maps?
A)Schmidt corrector plates
B)more sensitive spectrometers
C)switching from photographic plates to CCD imaging
D)use of interferometers
E)chilling the infrared detectors

Question

Quizplus · Accepted Answer

Interferometers greatly improve the angular resolution of radio maps by combining signals from multiple antennas to create a high-resolution image. The other choices do not directly improve angular resolution of radio maps. Interferometers greatly improve the angular resolution of radio maps by combining the signals from multiple telescopes to form a larger and more precise aperture.
