C)improve the angular resolution of radio telescopes.
D)increase the sensitivity of infrared telescopes to longer wavelengths.
E)speed up the processing of CCD images.

Question

Quizplus · Accepted Answer

Interferometers are commonly used in radio astronomy to combine signals from multiple radio telescopes, allowing for improved angular resolution. This technique is known as interferometry and can produce images with much greater detail than a single telescope could produce on its own. Interferometers combine signals from multiple telescopes to effectively create a larger telescope with improved angular resolution. This technique is commonly used in radio astronomy to increase resolution beyond what would be possible with a single dish telescope.
