In astronomy, an interferometer can be used to
A) improve the angular resolution of radio telescopes.
B) speed up the processing of CCD images.
C) decrease the effects of light pollution in getting darker sky backgrounds.
D) yield better seeing conditions with optical telescopes.
E) increase the sensitivity of infrared telescopes to longer wavelengths.

Question

Quizplus · Accepted Answer

Interferometers in astronomy, particularly when used with radio telescopes, allow for the combination of signals from multiple telescopes to simulate a larger aperture, thereby significantly improving angular resolution. This technique does not directly relate to speeding up CCD image processing, reducing light pollution effects, improving seeing conditions, or increasing sensitivity to longer infrared wavelengths.
