E) none of the above

Question

Quizplus · Accepted Answer

Interferometry involves combining the signals from multiple telescopes to achieve a higher resolution than any one telescope could alone. Therefore, it is used to improve the resolving power. It does not directly affect chromatic aberration, is not limited to specific wavelength ranges, and can work with radio telescopes that are thousands of miles apart. Interferometry is a technique used to improve the resolving power of telescopes by combining the signals from multiple telescopes to create a single image with higher resolution than is possible with a single telescope. It does not affect chromatic aberration or work exclusively for x-ray or ultraviolet telescopes. Radio telescopes can be separated by significant distances to use interferometry.
