Why astronomers use an interferometer?
Your eyes and brain form an interferometer, allowing for 3D imaging.
When several radio telescopes are wire together the resulting network is called a radio what?
When several radio telescopes are wired together, the resulting network is called a radio interferometer. This system allows for the combination of signals from multiple telescopes to achieve higher resolution images of astronomical objects, effectively simulating a larger telescope. The technique enhances sensitivity and detail in radio observations.
What is the main reason for using several radio telescopes together as an interferometer?
The main reason for using several radio telescopes together as an interferometer is to achieve higher resolution and sensitivity in astronomical observations. By combining the signals from multiple telescopes, astronomers can simulate a much larger aperture, allowing them to detect finer details in celestial objects. This technique effectively increases the angular resolution beyond what a single telescope could achieve, enabling the study of distant and faint sources in greater detail.
What is the resulting network called after radio telescopes are whired together?
When radio telescopes are wired together to work in unison, the resulting network is called a "radio interferometer." This configuration allows multiple telescopes to combine their signals, effectively simulating a larger telescope and enhancing resolution and sensitivity. Interferometry enables astronomers to achieve high-precision measurements of astronomical objects and phenomena.
What is interferometer in FTIR?
An interferometer in FTIR (Fourier-transform infrared spectroscopy) is a device that splits and recombines a beam of infrared light, leading to the generation of an interferogram. This interferogram is then mathematically transformed into a spectrum, providing information about the sample's chemical composition. The interferometer is a crucial component in FTIR spectrometers for producing high-quality spectra.
When several radio telescopes are wired together the resulting network is call?
Interferometer.
What is the significance of the distance between the two dishes in a radio interferometer with two dishes?
The distance between the two dishes in a radio interferometer is significant because it determines the resolution and sensitivity of the instrument. A larger distance between the dishes allows for higher resolution and the ability to detect fainter signals from celestial objects. This is important in radio astronomy for studying the fine details of distant objects in space.
What has the author Robert M Hjellming written?

When was Plateau de Bure Interferometer created?
Plateau de Bure Interferometer was created in 1988.
What is the interferometer used for?
It allows two or more small telescopes to achieve the angular resolution of a much larger telescope. This instrument is credited to Albert A. Michaelson.

What is the purpose of compensating plate in michelson interferometer?
a compensating plate is used in michelson interferometer to compensate the additional path difference of ray 1

What is the main reason for using several radio telescopes together as an interferometer and how does this technique enhance the resolution and sensitivity of astronomical observations?
Using several radio telescopes together as an interferometer allows for a larger effective aperture, which enhances the resolution and sensitivity of astronomical observations. This technique combines the signals from multiple telescopes to create a virtual telescope with a resolution equivalent to a single dish with a diameter equal to the farthest separation between the telescopes. This results in sharper images and the ability to detect fainter signals from celestial objects.
What is an example of interferometer?
An example of an interferometer is the Michelson interferometer, which is commonly used in the field of optics to measure the wavelength of light, test optical components, and determine refractive indices of materials. It works by splitting a light beam into two paths, recombining them, and measuring interference patterns to extract information about the light.
